Is Wikipedia a reliable and credible source of information?

I don't believe that Wikipedia is a reliable and credible source of information. Because I believe that if we need information, we should have accurate information. I don’t trust people to edit/add their own knowledge to a defention, because we all have different views on certain things and beliefs in life, which can mis lead alot of information that needs to be the actual defention not just what people think it means to he or she.
