It is the connections of those lifeless atoms and maintenance of those connections that produce life.<quoted text>
That is a claim you can make, but there is no evidence for it. And my basic point still remains: that *every* atom is your body is non-alive, yet those 'dead lifeless' atoms still combine to produce life.
While I am interested in abiogenesis, I don't have the technical knowledge of organic chemistry required to pursue the question in depth.
We have been working on the question for about 60 years. Less if you also require some knowledge of the genetic code. In that time, we have shown the basic building blocks of life spontaneously form under a variety of conditions. We have produced microspheres that are capable of catalyzing reactions required for life, that grow and divide. Given the the natural process on life took at least a couple of hundred million years, I don't consider that bad progress at all.
Mars has always been a borderline case for life off of Earth: a bit too far from the sun, low gravity (so the atmosphere diffuses away), and no other source of heat. Even if there was life on Mars very early on, I strongly doubt it would still be here OR that we would be likely to find unambiguous evidence of it. That there was running water certainly helps the case, but a lack of nitrogen compounds hurts it. I'd give it about a 20% chance of ever having life and about a 5% chance of our finding it even if it did.
I am much more enthused about Titan. It has a heat source from tidal action, has a wealth of organic compounds and has a decent atmosphere. It is still very cold and running water is an issue (although a ammonia based life might be feasible). I'd give Titan about a 10% chance of having life, although actual detection will still be another issue.
Let's face it. We have barely started to explore other worlds in our own solar system. But I certainly would not be surprised if Earth is the only body in our solar system with life. Even if it isn't, I strongly doubt anything more advanced than bacteria is anywhere circling the sun (other than us).
Now, when we go to other stars, the odds increase dramatically. First, we know that basic building blocks of life are common in the galaxy. We also know that stars with planets are very common (a fact that we did not know even 10 years ago). At this point, our techniques are biased towards finding planets that are close to the parent stars and so are unlikely to have life. But our technology is getting better on this. An oxygen atmosphere on another planet would be an almost sure sign of life there. And it is possible we could detect that even from here. I guess we shall see.
Place battery, light bulb, wire, and connectors on table.
Get back to me when they assemble themselves and light the room.
Oh, schedule a periodic delivery of fresh batteries until such occurs.
