"As for your claims of an undetectable supernatural, as I've also pointed out in the past, doesn't that have the same practical implication of it not existing at all?"
I never have said a Supernatural Creator was undetectable.
In fact, over the years, MY mantra has been, and remains :
"A God incapable of revealing Himself to me is of no use to me."
A little Priest said it best centuries ago:" He is within YOU...Look not for Him elsewhere."
You'd brand me an idiot if I denied the existence of dinosaurs because I couldn't find any strange bones in my backyard.
Yet you deny the existence of a Creator/God because you can't find Him in the only place you are willing to look.
