If you are part of a community, be it a religion or [say] a sciencentific discipline, you have to do the ritual dance around the campfire. Not because it makes sense but because that is the way we do things around here. That one community will kill you and the other won't talk to you anymore doesn't matter for the result.

There are lots of different bible worshippers but there is only one academia. There might be small differences of opinion they all preach the same "proverbial" creation myth.
