No Oxygen? Why not?
Ok, then you have a reducing atmosphere. Same problem. So you have metal hydrides, sulfides, etc. How is that better for propgation of life? All your organic molecules are presumably formed from CO2. They are then reduced, ostensibly to carbohydrates. Esters and Organic acids are reduced under such conditions, and the basis for metabolism of most creatures on this planet is negated (ATP hydrolysis, fatty acid synthesis, etc).
Having a reducing environment does not make for more gentle conditions, just different reactivity. Throw some LAH in water for a demonstration :-D
Life probably formed in a CO2 rich atmosphere, IIRC.
That's the problem. It doesn't matter if you remember, because no body knows. This isn't even science. It's assumptions and conjecture. The basis of science is a testable hypothesis. Unless you were there, it doesn't leave much for testing, now does it?
Scientists HAVE created the molecules that we believe are the basis of life in a lab. I guess it was not that lab you work in.
Please. I create the molecules of life all the time. I do NOT, however, create life itself. There is the problem. You can have all the ingredients for life, and not have life.
Imagine someone who dies. They try to resuscitate him, but fail. Why? Why does he die? He has EVERYTHING he needs to live, and yet does not.
I can throw all 20 amino acids together in a flask, add some acid (or whatever the hell else you feel is necessary) and not come up with an enzyme.
People make the mistake of saying "we have evidence that the molecules of life were here" and extrapolate that to mean "we found life!"
