This is such a stupid and idiotic question and such a easy one to answer.
Out of all religions Christianity causes the most harm. Its as simple as that and yet I see people asking this question for some reason.
Soon how? Im genuinely confused on how this happened. But if I'd have to guess I eould say luck. Its probably the most realistic answer.
1: One of the many arguments I see creationists use when trying to prove evolution wrong is "its just a theory" like the bible itself isnt a theory on how everything was created.
2: they deny actual evidence of evolution.(DNA and the fossil record) But they believe in something with no evidence?
3:they are just overall stupid.
