I find it rather funny that John's posting style here is characterized by dropping one-liners into threads telling us we're wrong because he's just smarter than we are and here he is fighting tooth and nail against creationism. What's next, flat earth?
It's been known that amino acids can be created by natural processes and recreated in a controlled lab experiment. I first found out about this as a kid watching Carl Sagan's Cosmos decades ago.
They've also been detected in comets. So the fundamental building blocks of DNA are just basic chemistry. The missing link is the creation of the first cell.
I watched a documentary recently on cable that does a pretty good job of explaining two ways in which DNA and cells could have evolved based on the makeup of the early earth. This includes pore or pockets in volcanic rock in tide pools and beside hydrothermal vents deep underwater. It's no surprise that life is so dependent on water, for instance. Water was the original "metabolism".
I know none of this stuff will convince John because he seems like quite a stubborn guy who latches onto a something and doesn't let go. If this thread is going to be nothing but trying to convince John he's wrong it will never end so I'm not going to keep trying to talk sense into him.
