@Irish Farmer: I admit that I'm no evolution expert, but what you've posted against the origin of life seems illogical to me.

Claim: Life could not have originated on earth because it would have been destroyed by oxygen.

But all the oxygen in the atmoshere was produced by life, like algae or vegetation. So where should the oxygen to destroy life should have come from when life didn't exist yet?


Claim: Life on earth is using only left handed amino acids, while spontaenous amino acid creation produces 50% left and 50% right handed amino acids.

But life is self-reproducing and thus also reproduces it's amino handedness. And since the similarity of all DNA indicates that all life on earth is a successor of one first primitive organism, it obviously also has taken over the amino acids of that first organisms. It was just by chance left handed - it could just as well be right handed.
