Before Big Bang there is God the permanent self-existent creator and operator of everything that is not God, after the Big Bang there is the universe that is created by God. So, the universe is the evidence of God's existence
You, like so many apologists before you, are saying creation needs a creator. Something can not come from nothing. Except of course the creator himself. You’re breaking your own rules. “Special pleading” fallacy. Won’t work.
Saying creation is evidence of a creator is circular reasoning. Another fallacy. We’ve been over this before, do you never learn ?
