Even if a god revealed himself or herself nearly 2000 years in one small part of the Roman empire (in Galilee, Samaria, and/or Judea), no god has revealed himself or herself to people living in our modern times, or even since the time of the Enlightenment (the Age of Reason). Certainly neither Jesus nor Jehovah nor a god that unknown to me revealed himself to me - even when I was an agnostic when I asked them to provide to me convincing evidence of their existence if they exist. That lack of complete lack evidence, despite my sincere searching for such, was one of the factors which contributed to me becoming an outright positive/strong atheist (meaning someone who is convinced beyond a reasonable doubt that no god exists) and a philosophical naturalist. That which which philosophers call divine hiddenness is one of the two strongest arguments which they cite for disbelief in the existence of all loving personal gods/Gods, even the biblical god (or gods) - the other being the argument from evil.
I agree with the idea of if (hypothetically) a god exists, then no human knows anything about that god since that god has not revealed himself/herself/itself to any human in the past 300 years. Furthermore many people living today are convinced that no god (even Christ) has ever revealed himself/herself/itself to a human.
For information about the concept of divine hiddenness see https://plato.stanford.edu/entries/divine-hiddenness/ . It says "However, “divine hiddenness” refers to something else in
recent philosophical literature, especially since the publication of
J.L. Schellenberg’s landmark book, Divine Hiddenness and
Human Reason (1993). In this context, it refers to alleged facts
about the absence of belief of God, on the basis of which one might
think there is no God. For example, Schellenberg argues that, since
there are nonbelievers who are capable of a personal relationship with
God and who do not resist it, there is no perfectly loving God, while
Stephen Maitzen argues that naturalism better explains the
“demographics” of nonbelief than theism and Jason Marsh
argues that naturalism better explains “natural nonbelief”
than theism. Understood in this way, divine hiddenness constitutes
putative evidence for atheism."
See also https://en.wikipedia.org/wiki/Argument_from_nonbelief , it says "The argument from reasonable nonbelief (or the argument from divine hiddenness) was first elaborated in J. L. Schellenberg's 1993 book Divine Hiddenness and Human Reason.
This argument says that if God existed (and was perfectly good and
loving) every reasonable person would have been brought to believe in
God; however, there are reasonable nonbelievers; therefore, this God
does not exist."
Schellenber promotes something he calls Skeptical Religion and Evolutionary Religion. Regarding them https://en.wikipedia.org/wiki/J._L._Schellenberg says "Schellenberg's Evolutionary Religion (Oxford University Press, 2013) aims to be a more widely accessible account of his arguments in the trilogy. It seeks to place these arguments into an evolutionary framework and maintains that skeptical religion provides a new way of responding to the science and religion debate. "
