I see a straw man argument.
Many people point to the irrationality in the depiction of God by the religions and their scriptures, hence jump into the bottomless pit of atheism.
Most atheists became atheists first, based on the complete and utter lack of evidence that any gods actually exist. Only after that do they start pointing at the very much flawed, inconsistent and contradicting ideas about gods as a very strong indicator that no gods have revealed themselves to mankind.
It is like saying our Earth doesn't have a second Moon. Not because your friend insists that this Second Moon is green or because his ideas contradict your neighbors idea that Second Moon is red, but because there is zero evidence a Second Moon exists.
And now you try to say that since it's possible the Second Moon is purple instead of red or green, I am wrong for thinking it doesn't exist at all? Yeah, no thanks.
The fact that there (theoretically) may be gods who are not even dreamt up in any current religious beliefs makes that their (theoretical) existence has even less impact on our lives than all the man made concepts of gods. In other words: why should we care about any gods that are unable or unwilling to present themselves in a compelling way?
