The majority you think?
I don't know but it's inconceivable to me that a belief can perpetuate without a shread of evidence.
It is baffling that religion is still a thing today but then again belief without a shred of evidence happens every day in our lives. Paleo diet, any of the diet fads, homeopathy, chiropractic, a2 milk. Not as crazy as believing in fairy tales like religion but it's pretty common.
