Absolute undeniable evidence for existence of God?

[Cheerful Charlie]

I often wondered what kind of evidence is actually required to prove without any doubt the existence of God?

Please note Clarke's "Any sufficiently advanced technology is indistinguishable from magic." Also, an advanced civilization might also be able to put you in something like the Matrix and show you all kind of crazy stuff.

So, could there be an absolute evidence for God?

No

Revelation. Which revelation? Christianity? (Bible) Islam? (Quran). Judaism, Mormonism, Hinduism? All claiming to be revelations from God by inspired prophets, rishis, poets, shaman s et al. Since there are so many revelations that must be false we must ask, since errors about revelations are so common, could it be that all supposed revelations are false and untrue? Yes. So revelation cannot prove anything. You'd have to demonstrate one revelation is true and that cannot be done.

Natural religion. proving God exists. The first truly notable attempt at this was by Plato in his work "The Laws - book 10" Plato aims his attempts to prove God exists squarely and explicitly at atheists. I will leave it as an exercise for atheists here to look this up on the net. Match wits with Plato. It is an interesting read.

Today, such natural religion attempts at proof are found in the Philosophy of Religion. A truly immense amount of ink has been spilled on the subject in recent centuries.

What is the consensus from philosophers of religion, the best, brightest and most honest? That there is no good evidence for God. No knockdown, does the deed proof anybody can point to. Natural religion started in earnest after the Greek skeptic writings were rediscovered and their techniques applied on each other, by bickering Protestant vs Catholic. Natural religion was an attempt to defeat such resurrected religious skepticism.

To date, there is no proof. Not from revelation, not from logic. 2300 years after Plato, proving god exists for once and for all has not succeeded despite centuries of some of the brightest minds in the world working lifetimes trying to do the job.

The roots of modern strong atheism go back to Sextus Empiricus, Carneades, Cicero, and then Hume and Kant among others.
