Kalos,
I have also read both of them in full. The second I agree with, science does not have a theory of abiogenesis, although that has nothing to do with atheism. The only thing that can be said is that any scientific understanding of abiogenesis will materialistic not supernatural.
The first link was meaningless drivel that answered nothing, however if you really want me to I can criticise it. Normally when I go through line by line and tear this sort of thing to shreds the poster normally slinks off never to be seen again. If however you are going to stick around and back up your link I am happy to oblige.
