OP -" At some point something must have existed without a creator"

So you conclude this how? Would it not be more probable and likely that nothing existed without a Creator? Nothing comes from nothing and something cannot come from nothing. Something can only come from something. You know this. And therefore since things exist they were created by that very original something which must be the Creator. We humans do a number on our brains, accepting crazy notions like the "big bang" theory as the origin of everything. That by the way is Kabahalist and occult in origin because their god is a "force"....an unknowable principal/law which set everything in motion. Which is easily ascertained as not the Creator because the big bang is "something" which could not have come from nothing. Therefore again we must acknowledge the Creator of all and everything - the designer of the laws of the universe and everything from suns to moons to humans - is an eternal Creator. But you conclude "that something must have existed without a Creator" which is IMPOSSIBLE.
