The problem I have with her being Luke's daughter is that she was dropped off virtually alone on Jakku without anyone really nobody watching over her. That would make more sense for a non-familial Jedi Academy student, but for Luke's own daughter, I don't see it.

I guess there is not much evidence that she wasn't watched over, but nothing in the movie suggested that there was somebody making sure no harm came to her.

Edit: Oops, I guess Max Von Sydow was there. Thought that was a different planet for some reason from where Finn and Poe and BB8 first encountered each other in the village.
