I'd suggest that the right similarities without enough would support the idea that religions are evolutionary by products or advantageous to societies.
And I would agree. But is that just our atheistic bias shining through? What similarities would we consider supportive of an evolutionary answer?
This would all have pretty much zero effect on our religious thinkers.
I suspect that some here would cite any similarities as being evidence of there being "something" out there. Something that is not just the product of human invention. I suspect they would consider our attitude to an evolutionary answer as akin to that of the religious you refer to.
So how can we hope to differentiate? Are there any clear predictions that an evolutionary answer could claim with regard to potential alien god concepts?
