Again we have to look at how God's are being believed.
Why do we? Sure how we believe in it, if we do, doesn't change what it actually is or isn't?
In my book therefore tales of carousing and shagging on mount Olympus are about as religiously edifying as tales of carousing and shagging at a New Atheist convention i.e. not very.
So they're not valid as depictions of gods because you don't like them? So does the billion or so feelings of distaste that the Muslim world has for the Christian idea of Jesus as an avatar of Yahweh invalidate that claim?
Claiming not to be able to compare the claims of the various Gods is pretentious nonsense.
I can compare them all day long. What I can't do is validate any of them.
You can equate God with being an old man with a white beard if you wish, In fact going back to the brain scan comparisons between the religious and atheists it seems you may be bound to.
Maybe, and you may be bound to some other more ephemeral, 'spiritual' or emotional sensation, but none of that validates any of the claims, either.
