We have come to a consensus on what constitutes scientific proof. What's the problem with some people wanting that same proof for the existence of gods?
You can demand proof, but other than our existence and the existence of the universe, there is no "proof" that you demand. God isnt confined to our world/universe.
What is outside our universe is UNKNOWABLE. Jesus said He is not of our world. By this He means far more than our "planet."
He also says the Father CALLS whom HE chooses.
Every Christian who knows God, only knows Him because He has REVEALD HIMSELF.
Computer generated beings, even when they become sentient, can never understand an existence OUTSIDE of their own universe.
Some things are simply UNKNOWABLE
