but after each claim they put a source, so just click on their source after you read something that they say to find out if its true or not. Wikipedia is very useful and many professors told me that if you use it correctly (clicking on the sources they provide) then it is useful. Literally 95 of all articles on there use sources to prove every sentence they say.

I knew you couldn't believe everything which is why I said "I guess this PROVES" instead of "I Guess they where right". Also teachers don't tell you not to use it because you can't believe it, they don't want you copy and pasting (2 guys in my history copied word for word and my teacher disqualified them.) but instead want you to look around for different sources. Most people use Wikipedia anyway and don't pay attention to the teachers.
