Why do many people disagree with evolution

In biology we were talking about it and many people in the class said it was bull and fake.

I know it's a scientific theory & you have the right to believe in what you'd like.

But I guess it sort of blew my mind that a lot of people don't think that it's real.

As with any complex subject, some people have looked at and studied the evidence and are just unconvinced (there will always be people who are particularly hard to convince, regardless of the idea that you're putting forth).

Some people have religious objections. Like you said, they have every right to believe in what they want. I have no problem with these people, but I DO have a problem when they try to claim that science supports their beliefs, since it definitely does not. If they want to reject evolution or science in general, they're certainly free to do so, though.

The overwhelmingly vast majority of evolution deniers that I've encountered do so through ignorance, though. They put forth long-disproved claims (usually parroted from creationist sources). They go on and on with one logical fallacy after another. Most of the time, they don't even understand what they're arguing against, falsely believing that evolution also addresses the origin of life or the origin of the universe. Like the parroted creationist claims, they're usually running with a version of evolution from creationist sources that's *intentionally* distorted and inaccurate, made so in order to be easier to disprove (a tactic called a straw-man argument).

The majority of people just don't have the foundational knowledge to really evaluate evolution, though. It's an incredibly complex subject, and unless you have a grad school-level understanding of biology, genetics, and biochemistry, it will be impossible to truly grasp. High school biology just barely skims the surface of the field, and is (unfortunately) focused on memorization rather than studying *how* scientists know what they know - knowledge that is critical to actually evaluating a scientific idea. Evolution is so far outside of everyday experience that common sense just doesn't apply... yet for some reason, people seem to think that they can make an informed decision about the theory, or that their opinion trumps thousands of scientists and 150 years of research when they don't even know what it is that they're arguing against in the first place.
