The earth came from two dust particles banging together in outer space right.
The universe has always been. It didn't start at
any time. It has just always been.
And anyways, even if a god does exist, it/he/she has long since died ... or given up giving a shit about us.
Either way, we're on our own. And when you die, guess what? You die. No afterlife. Just ... dust. As you once were.
Deal with it.
