Well, I live to believe that many scientests are merely a defending pawn of old and established, very fragile theory.
Evolution has never had any solid proofs. Stubborn scientists that have found themselves trapped in the "evolutionists circle" has no choice to escape. They can only maintain their lives and positions by upholding the very false theory.
Well, church scholars (dark age scientists) said the world is flat. They are wrong. Their faults and fraudelences had been proven wrong.
The same thing can be done on the evolution theory, only this time the challenge is larger : capitalization of the evolution theory.
Paleontologs are the easiest persons to blame. Without evolution theory, there won't be any of them. So they must maintain their jobs.
