If you ever deal with an atheist they will tell you that you have no proof that God exists.
And by God they mean YOUR concept of god, the all-powerful all-loving concept of Christian dogma and they would be right in stating that you have no direct objective proof that this specific entity exists.
If you tell them that Original Creation proves God exists, as you can't have original Creation without a Creator........
They would be right in telling you that your "Original Creation" is a theory or belief that you have chosen to align yourself to and that again you have not one shred of objective evidence to support it. You are free to believe in whatever you want, Leprechauns, Santa, Fairies or universes being created in an instant by a spoken word. It's extremely unlikely that any of those are real things.
They will think about that, and say... "well i just dont see it"...... And God knows that's true.
My strict fundamentalist grandfather held the same indoctrinated view as this and as Wrangler's subjective reality. He would say just look around and you can see evidence of design. And that's fine. But the problem is whose design? Christians are not objective. They are conditioned to be subjective and emotional and so like all superstitious people they simply look for ways to reinforce their belief system. So if they see something incredible happen, they immediately attribute it to God rather than consider any alternative cause. It's right up there with horoscope readers. They will attribute anything to their horoscope to give it credence. Just how it is.
Confirmation bias.
See someone recover from cancer . . . it must be god at work
See someone die of cancer . . . nothing to see hear folks walk on
Also,
You can tell them....."well, you can't prove that God does not exist".
Actually you can. Or rather you can prove that the specific concept of god peddled by the churches, the silly all-powerful all-loving Santa Claus god, doesn't exist. And we've covered this ground already. Innocent 5yr old child, Jimmy Savile etc
But beyond this, yes, we can't prove that A GOD or entity or entities do not exist.
And FWIW I very much suspect that numerous entities do exist, whether they be highly advanced more evolved humans or non-humans.
until you know for sure that God is a cosmic ray and hell is a myth...its best to just be quiet and wait until you know for certain.
and similarly until you see objective proof of the Christian god, not subject to confirmation bias, then equally keep quiet and stop psychologically abusing other people with BS scaremongering.
