maybe the reading many science books to explain how
life developed in detail during time is not as tempting
a to think :

"its just like it is, one entity created it all - we dont need
to know why, my parents told me so."

(strange that there are different dog breeds and portato variations..)

also: Evolution goes against the core bases of all religions,
that the humans have a superior.
If that superior did not created humans, it would not
be the overall superior.
Thats why evolution gets rejected without the need to
prove it.
Other beliefs, like the earth beeing flat and such, did not
go so deep into the fundamentals of the religion,
so they where accepted as wrong.
