First, your conception of evolution is flawed. evolution is not an antithesis to god. The existence of god and the existence of evolution are compatible. Proving evolution does not disprove the existance of god and proving the existence of god does not disprove evolution.

But the crux of tour argument is that because science can't explain the origin of life, god must exist.

I don't see the logic behind that. Science finds new knowledge every day. We don't know the origin of life YET, and we may become extinct before we become able to explain it.

Regardless, a lack of proof for one theory does not prove another. That's just not how logic works. Where two theories are mutually exclusive, actually disproving one does prove the other. But a lack of proof is far from a disproof.
