It could be possible that that both Gajeel and Natsu are indeed more than 80 years old and that Zeref knows Natsu.

How were they able to reach the present day? It's either they got sent to the future (together with their dragon foster parents) via some sort of a portal or put into a state of hibernation similar to what happened to them at Tenroujima.

Now why would they be sent to the future? Nobody really knows how long dragons are able to live but it is clear that Igneel's already alive since 400 years in the past. During that time, most of the dragonslayers would have been killed fighting Acnologia and without any dragons to teach dragonslayer magic to humans (since they're going extinct thanks to the black dragon), the chances of stopping the transformed dragonslayer became slim. Perhaps some people in the past saw that it is already impossible to stop the ex-dragonslayer's reign of terror so they decided that they need to "hide" a few dragons and some humans so they can be taught dragonslayer magic. The future seems to be an ideal "training ground"; magic is advanced and there won't be many dragons to kill, preventing the dragonslayers from becoming like Acnologia. They probably hoped the future has a greater chance at succeeding where they failed, so they sent them away 400 years ahead.

Who could have sent them to the future? I'm thinking Zeref had something to do with this. He could have changed during that time and personally asked Igneel for a favor like, take Natsu and raise him well to know love and friendship, avoid becoming an evil demon lord and make him strong enough to kill him and Acnologia(I suspect that Natsu is the demon E.N.D.). Him becoming immortal could be a side effect of sending them to the future... I just thought of kagero from flame of recca.

I don't know... I've already got a whole story running in my head. Now I just wish I could go into the story itself and ask freed to create the same runes he used to trap makarov which made us all nuts wondering why gajeel and natsu couldn't get out. Then I'll have natsu, gajeel, wendy and laxus trapped inside to see if any of them can escape.
