How any creations deny the possiblity of evolution is beyond me
I think you meant "creationists" in which case I can explain that.
Creationists, and all Christian Nationalists aren't interested in the facts. They are interested in the Bible. Everything that exists that might contradict the bible is considered a ploy by Satan to distract people from the truth.
With compelling logic like that, we are in big trouble, since these are the people curently involved in running the Republican party of the US, and running for state and local school boards.
Of course you can't say they are wrong, because then you are attacking their religious beliefs.
