1)  My explanation is that Luffy will destroy FI in the future when the fishmen will with that huge ship in the surface..

2)Just a unique ability that Oda did with GDR and Luffy so he show that they have great instict and many things in common..

3)I am pretty sure are DF ability is something with strings, but well u never know

4)Maybe a god create them. or the ancient people somehow took the fruits from the sea and that is the reason they are cursed..

5)Maybe a war and that is how the nobles-marines-pirates was created..

6)Something from skypiea since its uranus(oυρανός= uranus=sky in greek language)

7)Probably Danger-don't enter
