Humans are a funny species. We do all kinds of things that don't make any sense (including religion), but let's see how religion stacks up to all the other silly things humans do. I'll post a few things in the comments section, then reply with a score between:
0: Not silly at all
and
10: As silly as you can get.
Please add more comments so we can get more replies.
I think you should check out Yuval Harari's "Sapiens".
The Jewish Religion: Judging by a variety of different criteria, (IQ, Nobel Prize Winners, Professors at top Universities, etc.) Ashkenazi Jews are the smartest group of people on the planet, but many still cling to a bunch of crazy fairy tales, many of which have been soundly disproven by other Ashkenazi Jews.
Jews are the best achievers because only the smartest have survived millennia of persecution This is the greatest irony against the bigots
