Maybe the dragons didn't disappear on July 7 x777, they just sent the dragon slayers to that time or was Zeref with the eclipse, the dragons did say that they can alter memories just like they did to Sting and Rouge. Also the time they were alive with their kids don't add up many people through out the series said dragons died 400 years ago yet at least 5 known dragons were still alive recently, they are not small so hiding could be difficult (except Acnologia that can switch forms and was human).
