Life, like everything in the universe, including the universe itself, is the random confluence of sub-atomic particles.
Where did the particles come from?
That's unknowable, but if you want to credit your god, Ralph, that's as good a guess as any. Just be aware that if god created the particles, he/she didn't show any interest in them afterwards. That's knowable by casual observation alone.
No interest? Seriously? I don't even know where to begin with that stupid comment, except to wonder if you've ever read the Bible. God sent His Son to die for us. If that's not taking an interest, then what is?
