Ok. I don't want to spoil this for everybody, but I'm going to. And for clarification, this isn't a theory. I read all this in a translation of the game.
As I'm sure you all know, there are rumors that Master Eraqus said that Ven shouldn't exist. In the game, this takes place after Ven finds out that he was created by Master Xehanort (MX) and that's when ME tries to kill Ven and Terra steps in a kills ME.
So who is Ven? Ven is a copy of a person made by MX to get the X-blade. MX couldn't get Ven to create the X-blade, so he created Vanitas from Ven's darkness. Vanitas later goes on to make the X-blade just before he's defeated.
Also, people should easily realize that there's no way that Vanitas could have been created at the same time as Sora's heart. The events of the game take place in a fairly short amount of time and Sora is 4 or 5 years old when Terra meets him on Destiny Island (DI) during the game.
So why does Vanitas look like Sora? It's really simple... Ven, just like Xion (but a little bit different), is a copy of Sora. It's just that Xion was an imperfect copy (and so she stole Sora's memories and gradually started to look like Sora) and Ven is a copy of Sora's light. Sora is "the chosen one" (for lack of a better term) and he's somehow tied into this whole mess (though I'm not completely sure how yet). So when Vanitas is created, he takes on the form of Sora.
Why does Vanitas look different than Sora? Because 1)Ven is older than Sora is currently so he mirrors Ven's age. 2)Vanitas is an Unversed, so he's got different features than the original Sora (black hair, yellow eyes).
