"I dont think I'll go beyond this matter. I've laid my side out and you obivously don't agree
so let us sit at that."
What I don't agree with is your willful continuation of the ill-informed argument regarding The Big Bang.
The problem is that you seem to believe there are only two sides to the argument. One is that the universe came from nothing, the other is that the universe came from nothing but this nothing had something living in it to make it happen, but there are actually three sides to the argument; The universe came from something, and that something is natural.
As for your cute belief that String Theory is unproven and unprovable: Keep researching
