Ok, someone asked me this question, I"m copying and pasting below. I don't even understand the question, let alone have the answer. I actually have absolutely no clue what this person is even talking about. Help me out guys!! 
"Why don't christians believe in reincarnation when jesus clearly teaches it???... you can't get much clearer-- John the baptist was Elijah reincarnated..
"Behold I will send you Elijah the prophet, before the coming of the great and dreadful day of the Lord." (Mal. 4:5)
--"For all the prophets and the law have prophesied until John. And if you are willing to receive it, he is Elijah who was to come." (Matt. 11:13-14)
--"And the disciples asked him, saying, "Why then do the scribes say that Elijah must come first?"
But he answered them and said, "Elijah indeed is to come and will restore all things. But I say to you that Elijah has come already, and they did not know him, but did to him whatever they wished. So also shall the Son of Man suffer at their hand."
Then the disciples understood that he had spoken of John the Baptist." (Matt. 17:10-13)"
