When there is no physical evidence, what made you decide there is or are gods? Do you care about lack of proof? How do you experience this/these deity/deities?
Only materialists believe that nothing but matter exists. The only evidence they can accept has to be of objects and processes that are physical. However, by most definitions, God is not at all material. Therefore, materialism cannot address God as a non-material category, and cannot accept non-material evidence for God's existence.
"Show me your God" is therefore an inept demand, because God, as a non-material category, cannot be "shown" - that is, cannot be seen or perceived by the senses.
Obviously therefore, science cannot be used as a God-finding tool, since science deals only with matter, and God is spirit.
Neither is philosophy a competent tool in the God-quest, because as the late atheist social critic Gore Vidal wrote:
"
God, or what have you, is not to be found at the far end of a syllogism, no matter how brilliantly phrased."
This expresses the simple fact that philosophy has been used both to "prove" and to "disprove" God.
It also expresses the idea that the kind of God found or rejected via philosophy will always only be an abstraction, of intellection, not of "existential" knowing.
The only other alternative that I'm aware of is the question of God not as an object of philosophy or science, but of experience - mystical experience, the experience of divine communion and divine union - i.e., of God as an inner experience of a living, transformative "Presence" in the soul (soul defined as our deepest subjectivity).
It is obvious that the God-experience as such is impossible to pull out of the personal psyche into the external world for public confirmation or de-confirmation. No one but the "seeker" him or herself can access the God-experience. No one can do it for them. It's a solitary venture.
So calls for "proof" of an entirely subjective experience are unskillful. The response from experiencers to non-experiencers can only be invitational - that is, to invite the questioner to duplicate whatever processes, if any, led the experiencer to the internal God-experience.
So in my view, the God-question can only be resolved through "the journey within" - and the solution has nothing to do with the category of "proof" in its common connotation of publicly-duplicated, quantifiable claims.
