Why is Harold Camping trying again?

I'm 15 and a girl and I just want people's opinions.Today he issued a statement."I was wrong,it's October 21st now.",to summarize what he said.Now he was wrong in 1994,he was wrong 2 days ago and now he is trying again.Do you think many people will believe as much as they did before or will his words just fall flat again?In my opinion,he is a false prophet for he has already been wrong and when you claim to have said God told you something,you can't be wrong because God is never wrong and this man pretty much contradicted the Bible and called God a liar and I,being a Christian,believe that he will answer for such thing.
