Why is evolution so controversial?

This was on the internet news today..... Pope Francis declares evolution and Big Bang theory are right and God isn't 'a magician with a magic wand' I like that guy! I honestly don't think that there was a literal creation as many claim happened in Genesis. I know Faith will think im being blinded by satan, but im just being honest. Who knows? Maybe Ken Ham and them are right, but if so it would lead to the question of why God would trick mainstream science.
