I don't see why evolution is assumed to preclude some other, intelligent force. - Julia Orwell
No one can prove a negative, like 'there is no God', so there is no preclusion going on (though assumptions of preclusion might be). He might exist but not have created the life we've seen, thus there is no evidence for Him in the origins or diversity of life.
I think it's more that evolution gives a good enough explanation by itself , thus there is no need for God (or ID) to explain how anything happened and that leaves us no reason to include Him in any explanations.
Absence might seem like preclusion, but really its just absence: absence of Someone for whom there is no other verifiable evidence. There's nothing to give one cause to believe in God apart from faith, and that's down to the individual.
[Thanks cantleave! LOL! Abiogenesis, not evolution, refers to the origin of life. Edit duly made.]
