Truth: the Vikings would plant animals on land along with foods. Then they would travel around and come back to the island with all the good food. Now after a while of being away you can only imagine how this new island looks when they return. So much good food.
Theory: God planted us humans to one day come back and eat us. History repeats its self
...a great person told me this once and I stand by it, maybe he will come tomorrow and eat us all that way i wont have to go to class :D
