I think that Natsu, Gajeel and perhaps Wendy were from a different timeline and thats how Zeref knew Natsu, Also that would explain how Gajeel and Natsu couldn't exit the barrier (you had to be under 80 yr) Freed put up in the fighting festival arc. So perhaps Zeref knew natsu or... could have been his father?---Could be explained when Zeref cried when he saw Natsu Just random theories
