That doesn’t compute to someone with a completely materialist view of the existance.
The universe includes everything material.
It had a beginning, and the big bang still resonates to prove it.
Anything that has a beginning has a cause.
That cause must be external or transcendent to the caused.
Scientist cannot get beyond what was before the big bang. I believe God is the Cosmic Singularity, which is why scientist have hit a brick wall when trying to discover what "WAS" before the big bang.
Sorry, I didn't address this.
God IS the beginning. He didn't come from anywhere, he was always there.
Either one believes this or they don't.
