So you should study biology then. Here's a great place to start.
Biology 101: Intro to Biology
Interesting but is this the same science where every 100 years or so another generation comes along and proves the last generation didn't have a clues as to what they are talking about. Not saying today's bioliologists are wrong about their findings but history shows this always happens to every generation of scientists, philosophers, and so-called intellectuals in the past. Imagine those poor convinced people who had to sit thru those boring debates not knowing 100 years later they dooped. All i'm saying is keep and an open mind my friend because you never know. You might be waisting your life on certainty that will be proven wrong 100 years down the line and not even make again in any debate. Can't say that about the Bible even when many people don't believe it and think they've proven it to be invalid. It at least makes it to the table after many centuries.
