At one time, I wondered
what I should begin to think 'God' might truly be.
Well, a lot of time has gone by since then
and it is a never-ending process .... but yes,
and without a doubt, I know it to be a fact that God does exist.
A fact is a verified, corroborated, definitive point of datum that has been proven to be true.
The existence of any god is a subjective belief only and there is absolutely no objective, empirical, confirmable, testable evidence to support the alleged existence of any such entity. None.
If you disagree with this, then present the aforementioned evidence that satisfies each of those requirements and can be subjected to rational scrutiny.
Yes. It's also a fact that I'm happy today. Now, I can't prove either one, and those who ask for proof are either jerking your chain for giggles, or don't know any better.
In life, proof is the booby prize. Prove your wife is beautiful or that that Picasso painting is awful. Prove you are hopeful ... prove you know God. Same thing.
Can you suggest a way that hundreds of millions of intelligent people could know Him and live in daily relationship and communication with Him, if He didn't exist??
