Why would anyone believe that life can come from magic? That’s what intelligent design amounts to. It’s not more believable than evolution and abiogenesis, it’s less believable. It’s a fairytale.
Abiogenesis makes sense to me because the building blocks of life do or can arise naturally. Can life? Probably, given the right circumstances. I can’t prove that and I’ll admit it, but I would ask you the same thing you asked us: can you prove that god created life?
