Maybe all of the dragon slayers were taken to another world like with what happened to Lisanna in Edolas. Because it would explain why Natsu never encountered any other humans before 7/7/777 (at least that's what I think). And before/ after they were moved, they had their memories fixed so they could remember certain things. As for the age thing, maybe they had been frozen in time like what happened with the Tenrou group
