When they think of life on Earth, most people believe we are about half way through the journey. Not exactly. The oldest microfossils, found in the australian shale in 2011, date to more than 3.5 billion years ago. They are cyanobacteria that lived in a low-oxygen, hot volcanically active climate, but cells they were. Shouldn't we have at least another 3.5 billion years to go before our sun even begins to think about going into the red giant phase?
In short, no. Our son, sol, is a variable star, and its total energy output is slowly increasing over time. Some 800 million years from now, the total energy output of our star will be such that the oceans on Earth will boil away into space.
So the surpriseing fact is that, although creatures like us have wandered around on our planetary surface for just 2 million years or so, something like 80 percent of the history of life on Earth has already taken place.

Interesting info...seriously don't think we have nearly that much time...think about it...overpopulated, not enough food, water will become short...this isn't only the US but worldwide...

I agree, and life has already almost became extint twice in the history of our planet. Just look at the moon, most of those craters were during the late bombarment, which astronomers now think occurs every so million years. They think this happens when a unknown planet, or star, gets close enough to our solar system that its gravity interupts the asteroid belt between mars and juipture. This would cause the asteroids to be hurled toward the sun and earth. They say that we may very well be entering that time zone right now. They may be correct, with the lastest about the asteroid in russia and south america. Lets hope they are wrong.

just your life over Jesus and redeem yourself with the good lord and maybe we will not be left behind, when it is our time to go; or as the world comes to an end. may god bless you and your family.

There are some scientist that say that carbon dating is NOT really that accurate. If that's true, then none of us really know how old the earth is. Look it up. I am a Christian but I don't ascribe to the theory that the earth is only six thousand yrs.old. The bible says that God made the earth and the universe in only six days. Then you see the time line in the bible and it seems that it's only around 6000 yrs. But, the bible also says that one day is as a thounsand yrs and a 1000 yrs. is as 1 day. God could have made the planet and then waited millions of yrs before he made man. The dinosaurs were in there before man. The only mention of ANYTHING that could be a dinosaur in the bible is Numbers 13:33 where they saw "something" that was so big, they felt like a grasshopper next to them. It says they were giants. It also says that they were the decendants of Anak but I believe they saw dinosaurs too...Time has no meaning to God because He is timeless. I am one of those that believe that science and religion can co-exist and BOTH of them are right. God could have worked through evolution to achieve His goals. However, We did NOT come from monkeys or fish. The theory of evolution has so many holes in it that it can't possibly be all the way correct... The bible says that His ways are above our ways and His thoughts are above our thoughts, so He could have done it ANY way He wanted to because he holds ALL power in His hands. He can violate the laws of physics because he made them.

I know this is a little early, but maybe you guys will find this interesting? Late this november and december comet ison will appear. If you have a large telescope with a ten inch mirror or larger you can see it now as it approaches juipture.
Anyway, if all goes as they say, comet ison will appear so bright that it can be seen even in mid day.
If that's the case, then it should be as bright as the full moon during night time.
With the scare of 2012 and ppl acting as they did, it will be interesting to watch how some ppl will react to this. don't worry, it's no way near Earth and is in no danger of impacting our planet. Just a good night show.
However, in 2014, there is a asteroid that will come extremely close to Earth on its way from behind the sun. This is the same asteroid that near missed up this year on its way toward the sun. But this time its orbit will bring it at least as closer to earth then our own moon. Astronomers are still doing calculations as it appears they themselves are uncertain if it could impact Earth, that is how close it will come.
And this my friends is no 2012 myth, this is true astronomy facts.

Blah, Blah Blah, The earth as we know it will be around for at least 1000 more years. Albeit, most of the earths population will be WIPED OUT in the next few years. Read the only book IN THE KNOW to find out a first hand account of not only earths past but also the future of this world. Of course I'm talking about the AV Bible. The AV stands for Authorized Version. It also can be applied
1 Timothy 6:20-21
O Timothy, keep that which is committed to thy trust, AVoiding profane and vain babblings...
Like the THEORY of Evolution.
...AND OPPOSITIONS OF SCIENCE FALSELY SO CALLED:
Which some PROFESSING have ERRED concerning the faith.
This Nation is full of PROFESSORS who have ERRED CONCERNING THE FAITH!
Does in not say in the bible that ' wormwood ' will hit the earth? Wormwood is surely a comet or asteroid. Again, science and religion go hand in hand.

I look forward to seeing comet Ison,sounds like it will be a great show. Even more so than comet Hale-Bopp was when it was very visible in 1997. As far as peoples reactions I'm sure it will be almost as interesting as the comet itself...remember Heavens Gate?

This is a cut and paste article that was written by a stranger in the comment section of a website called the Philosophy of Science. This is NOT a strawman attack. Friend, there are so many holes in the Theory that if it was a boat it would never make it out of the marina. It would sink. If you would set your bias aside and just do some serious research, then you would see the holes. Read this and then tell me what you think. Can we keep this civil. I don't mind debating but I really don't feel like engaging in a war of insults. Thanks...

" My opinion of evolution is that it is wrong. Here is a brief overview of the evolutionary theory. It is believed that all of life as we know it formed from life before us, that was a lot less complicated. A bacteria, slowly underwent changes through deformities and just genetic changes in offspring. Now, Charles Darwin was a man who in term, discovered evolution. His ideas were shown that the stronger offspring with a better genetic blueprint, would more or less survive longer to have more offspring than the weak. The weak would then completely die off, leaving the offspring of the stronger organism to continue.



Here is where I begin to disagree. This would be very true if the environment were very, very controlled. However, I think that even the natural instinct of animals, especially humans, counters this theory. As you know, we are constantly fighting for a cure for cancer. Well, this is one way that anyone who has the genetics that make them immune to cancer pass it on. Now I am not saying that the world would be a better place if everyone with cancer would just die already, I am saying that because of the our natural tendencies of helping the weak progress, that evolution has either come to an end at humans, or it has never been able to happen. It is also apparent in animals that they protect the weak from death. Another argument I pose to evolution is systems. The systems of the body are a very delicate thing, without even one type of organ, the system would completely shut down. meaning death. So obviously with evolution, there were organisms without organs. So let me ask this, did the systems appear one organ at a time? This would make sense if the organs were independent, however they aren’t. So an organism with a stomach could not benefit without lungs, or a cloaca. If an organism had only part of a system, it would not benefit the organism, therefore, natural selection would not take its coarse in completing the system.

One last argument I pose. Many evolutionists say that its logical that everything has a beginning, but what is the beginning of the first thing. Does that mean that logic had a beginning? Even if the big bang happened, what exactly made that possible, that compact ball of matter didn't come from nothing."

There is SO much more but I don't have the time to look it up. Don't just take the "Man's" word for it. Do you not know that there are so many scientist that have disavowed the Theory of Evolution now that it will one day collapse. I'm not saying that they are ditching the theory of evolution in favor of a Creator, but they now know that the theory will not hold water anymore. Schools still teach it as fact because of pressure from atheist groups that shudder at the possibility of creationism being taught. I am a Christian that does believe in creation, however, I believe that God used some form of evolution to achieve this.(Not the way you think) Let's just leave God out of this for the time being. If we did not come from evolution then what did create all of this? Was it an intelligent designer or aliens? For many years, the theory of evolution was accepted as fact but there have been new discoveries that have questioned that theory. Remember, they don't call it a "theory" for nothing. Theories can change

Religion is notorious for conceiving an idea and then trying to make it true, either by propaganda or sometimes by force. While science makes a discovery and then immediately sets about trying to disprove it, just to make sure it’s correct before everybody makes idiots of themselves.

I have no idea why my first response didn't appear so I'm just going to keep it short.
Science isn't a "philosophy". It's a well-disciplined method for separating reality from fiction. "Religion" is a philosophy.
I asked for just one "hole" in evolution from you that wasn't a straw man and you copy and paste from a site that is obviously nothing but straw man. So you've not only failed but failed miserably.
But thanks for playing.
That's just what I would expect from someone without enough intellect to logically debate the subject. You throw out a couple of "witty" insults in a poor attempt to make yourself "appear" to be intelligent and to be "above" even responding to my post with anything that resembles a logical answer. Sorry, You FAIL. It's easy to just write off an intelligent response as a strawman, but really now, you can't even try? Yeah, you asked for one example and I copied and pasted a full page. Well, I had to choose which one to use because there were so many holes to choose from..lol....C'mon man, you can do better than that can't you? If you don't break down my response and tell us just why you think my comment is a strawman then you must not have the intellect to do it....Sorry, you fail again.

Your "holes" are straw men. They falsely state the opponents position as though it were fact and then proceed to attack the false position; notably, your portrayal of evolution as some untested "guess" that science it attempting to back away from. That is a blatant lie. One need only avail themselves of any modern high school level biology book to discover so. But evidently, it's easier to copy and paste from an apologist site with an agenda, that probably hasn't been updated since 2006, than to actually investigate the opposing position.
You fail. Pitifully so. But you can feel free try again, "Scarecrow".
That's the problem. High school textbooks. They still teach evolution as fact when the truth is a lot of scientist are not sure anymore because of recent discoveries within the last 40 yrs. Don't take my word for it, look it up yourself. I can look up more and copy and paste some more but you would just belittle that so there really is no point in me debating with you. You would not believe anything that I would post even if there was photographic evidence to back it up. Like I said, Look it up yourself. But first, you MUST set your bias aside and search for the real truth no matter if you like it or not. That's what I've done. I'll admit that evolution has some intriguing points but there are also many questions that can't be answered. There are "missing links" in EVERY species and you know it. Also , how can anything "evolve" when most species have very complex systems that require multiple parts that can't function without ALL of the parts working together? How can that be when evolution says that these parts evolved at different periods in time? It just can't be. High school textbooks are teaching things that have been disproven, but yet they keep on teaching because of people like you that are too scared to admit it. You are scared that if evolution is not the way we got here, then the creationist ideas will pick up steam. That's not always the case. There may be other ways, but evolution is not the one. Do your own UNBIASED research and then get back to me.

And mapping the human genome wrote it in stone, sealed it in concrete, and put that puppy to bed once and for all. Evolution is a fact and the only people who argue against it do so from ignorance, willful or otherwise.

I did. That's why I understand and accept evolution over superstitious mumbo-jumbo.

guest wrote, "But first, you MUST set your bias aside and search for the real truth no matter if you like it or not."

I suggest you take your own advice. Funny how when someone wants to know something about religion they don't ask a biologist. But there's no shortage of religious fundamentalist nuts who make authoritative statements about biology when they have no idea what science even is or how it works. If you want to understand biology then go to the source. And that source isn't an apologist with an agenda.

guest wrote, "I'll admit that evolution has some intriguing points but there are also many questions that can't be answered."

And they will never be answered as long as gullible people insert "Magic Man In The Sky" into the gaps. But sorry, evolution isn't one of those areas. Evolution has been proved to the point that continuing to argue against it borders on willful stupidity.

guest wrote, "Also , how can anything "evolve" when most species have very complex systems that require multiple parts that can't function without ALL of the parts working together? How can that be when evolution says that these parts evolved at different periods in time? It just can't be."

Irreducible complexity has been debunked in the laboratory, and the goof-ball who invented the idea (Michael Behe), was finally forced to admit he was wrong in a court of law.(Kitzmiller vs. Dover) Look it up yourself.

guest wrote, "High school textbooks are teaching things that have been disproven,"

Evolution is proved. Conclusively.

guest wrote, "There may be other ways, but evolution is not the one. "

There are no "other ways". Evolution is the only existing explanation for diversity of life forms, period. That's because it's a fact.

guest wrote, "Do your own UNBIASED research and then get back to me."

Again, take your own advice. When you can prove magic as a viable alternative to science, then you can get back to me.
It cannot be proven. It's only an educated guess. You can't prove anything from millions of years ago. I'm not saying evolution isn't real but saying its fact is ridiculous. Just because people who want to believe its fact say it is doesn't make it so. Most of science is partial guessing anyway. We keep hearing different thing about our solar system, you would probably call these facts, but no one has actually been there. They are just guessing and relating it to what they know.

Were it not a fact then I would agree. But evolution is a fact.

True. Which is why evolution passes the "test" to verify it as fact. There's no "belief" required.

You don't "believe" planets orbit the sun?? Or maybe if you fall off a cliff you "believe" you can "guess" yourself from hitting the ground??? How about germs? Are they just an "educated guess"?

Tell ya what, Sport - the next time you go to the doctor with something that seems serious just diagnose yourself and tell him he's only allowed to treat your diagnoses because he can only "guess" anyway.
Lol. It is not proven. How can you keep saying this.
