I think the biggest problem people seem to have with evolution is understanding what it means.
Many people that I encounter who deny evolution seem to have the misconception that evolution has something to do with planetary sciences, cosmology, or any other sciences apart from biology for that matter. I honestly have no idea where they're getting this. Evolution applies
only to the gradual change of species over time. It also says nothing of the origin of life (people probably get confused since Darwin's book is titled "The Origin of Species" by which he meant the origin of the diversity of life, not life itself) that would be Abiogenesis, which itself is a very sound theory.
Additionally, most people seem to generally attack "evolution" itself, confusing it with Darwin's theory. Evolution isn't a theory proposed by Charles Darwin, it's an observable trend in the fossil record. The Theory of Evolution by Natural Selection, however,
is the theory proposed by Darwin which details the mechanism which produces the observable trend of evolution. Evolution and Natural Selection are not inseparable. This however doesn't make Darwin's theory any less reputable or true. After many years of refining Darwin's initial proposition, scientists have by in large concluded that the theory as it stands now has been proven to be demonstrably true, remaining a theory only to compensate for new data or future modifications which may not be evident to us now.
Those who imply "it is only a theory and can therefore be entirely wrong" do not understand what a theory is (for instance, gravity, black holes and even germs that cause diseases are still theories.) Those who look at the fossil record (though often choose not to,) observe the ways in which humans produce the same effects artificially (the various breeds of dogs or the existence of cattle as they are today, for instance) and even partially delve into the plethora of other evidence for the existence of evolution while still with-holding the position that it doesn't have a modicum of merit are willfully ignorant and stupid.
Makes my blood boil.

Interesting that most people would say yes since we share that much DNA with chimpanzees. But that's just a coincidence i suppose...
Phylogeneticly speaking, sharing that large of a percent of DNA with another species is definitely not coincidence. Granted, since we all stem from the same origin, every species on earth shares certain percent of DNA similarity (we even share a certain portion of our genes with trees! Something like 40 percent. I can't remember exactly) but a >98% genetic similarity is undeniable proof that chimps and humans most definitely shared a common ancestry in the not-too-distant past.

It also amazes me that most people who believe in evolution think it's possible for animals to evolve over millions of years, but not humans. We had to start somewhere. We didn't just pop here out of thin air...
That's right. Most people say "if we evolved from monkeys, how come there are still monkeys?" (a question that gives me a terrible migraine, to be honest) to which I reply "because we're still monkeys now."
