Why is it possible for a speck or whatever that has been around for an indefinite amount of time to explode and create the universe as we know it, but it's not possible for there to be a god that has been around for an indefinite amount of time to create the universe as we know it?
Not exactly evolution but I'll try
It's possible a god created the universe, but at the moment the big bang theory is the most viable model for the origin of the universe. A god
could have initiated the big bang, but that can neither be proven nor disproven so it isn't actual science. All we know is the universe is expanding, celestial bodies are redshifted, and cosmic background radiation suggests expansion from a single point. All of that is evidence for the big bang.
