I have my own theories for that on Carrot's blog. Also Natsu and co. could have been frozen in time as children and would have woken up in x777 with no Dragon parent in sight. Also Daphne was adult when the other FT characters were young so maybe she saw a Dragon before they disappeared in x777. Also Faust is in Edolas, maybe when the gate opens the Dragons are transported to Edolas for a few years and then return to Earthland.
