One universe = One God. Therefore, one "God-truth." For millennia, human beings have tried to articulate it. As I said, this is a "work in progress," an open question. To refuse to engage it is to destroy one's own humanity. JMHO FWIW.
The asymptotic quality of human consciousness is a condition of human existence; that is, to physically incarnated human being. The spiritual dimension of a man, however, extends beyond the asymptote. For man is more than physically incarnated being.
This has been the great insight of mankind down the ages, West and East.
This also happens to be the "inconvenient fact" that totalizing nihilists driven by the will to power would most like us to forget. It makes for easier prey....
Why? While that seems to be the trend in these parts lately, there are plenty of cultures that have, with equal confidence, asserted the existence of whole football-teams worth of gods. Such was the nature of one of Hume's objections to Aquinas.
Of course, Occam's Razor suggests that we should not unnecessarily multiply entities. But that would seem to imply that the most parsimonious explanation is to postulate zero gods. Which I, like you, find rather unsatisfying ;)
