In Wall-E, they said how they have been aboard the spacecraft for around 900 years, but how would you keep food for 900 years without it rotting or going to Earth. I mean they haven't even seen a plant in over 900 years. Also, people don't live for more than 200 years, so where do they get rid of all the bodies? Why are the people so fat? I'm assuming that there so fat because they're eating other people's body fat. - Sorry if this is creepy. I'm just wondering, and giving out my opinion.
I believe that Anna and Elsa's parents didn't immediately die during their ship wreck. I think that they floated on pieces of the boat and/or cargo and made it to mainland. While they were there, they had a baby, and lived for many years until they died in different ways. This baby was Tarzan.
