Yeah just go and create the big bang and start another universe.... easy, no prob, simple as that.
Still not falsifiable because the god in this new universe will still be invisible.
I can't see you either. You're not invisible.
Well I respond to you in a way that everyone can see.
If we both had the time and inclination we could arrange a meeting.
I could send you pictures, videos, and a list of people who presently know me.
God is invisible and undetectable, I can not arrange a meeting, and I can only ask people who have never met the guy what they think of him because he is undetectable to them as well except for feelings they attribute to him. I think those feelings are manifestations of the mind body not a measure of his existence. I cite as my proof that every religion from aztec to egypt, from islam to Christianity,from hindi to spiritualist, all claim to have feelings where god made his presense known through subtle cues that could be anything from the ID, caffiene or a bad piece of fish.
