What is the prophecy in the 5th harry potter movie?

I dont understand it, they never explain what it actually is!!!

Harry and Voldemort can not live in the world togather. They are too powerful and both fear the oter for different reasons. Voldemort knows Harry is very angry that he has killed the people he loves, so Harry wants more than anything for Voldemort to die. He even said that he would do anything to destory the rest of the Horcruxes then kill Voldemort him-self. Harry knows Voldemort wants him dead so that no one will question hs power ever again. He feels te only way is to kill Harry.
In the prophecy it says that "neither can live while the other survives". Now what the prophecy is , is what Professor Trelawney said or prophiciced what would happen. Now it could have been Harry Potter the-boy-who-lived(which he is) or Neville Longbottom the-boy-who-lived. Voldemort chose Harry not because he knew it was going to be him but because Harry was like him. Harry is not full "pure" wizard. His mother Lily was muggle born. And Voldemorts Father Tom Riddle was a muggle himself. Neville is "pure-blooded". The prophecy also says that "the parents of the boy had thrice defeated the dark Lord". Both Harry and Neville's parent had done that, not in the meaning that they killed or stopped him but as in got away.
Now only two people heard this being said, One being Dumbledore who heard the whole thing, and the other Severus Snape, who only heard part of it. Snape went to go tell Voldemort the part he heard. Voldemort then picked Harry Potter as the boy who was supposed to kill him. Snape felt bad and that is when he turned spy for Dumbledore.
Now after 15 years of not knowing the whole prophecy Voldemort need it, he needed to know what he would have to do to kill Harry. Although only the people who the prophecy are about can take it off the self. Before Voldemort picked Harry it was game to Harry and Neville. After Harry became "the chosen one" it changed and had his name on it.
Now Voldemort did not want to ge it so he used Harry, but it broke so neither of them got to know the whole thing. But Dumbledore had heard it so he told Harry the rest of the prophecy. So now only Dumbledore and Harry know the whole thing. And that my friend is what the prophecy is.
