Odin: Yes, your fathers and I did travel back in time but you can ask them about that tale. Now as far as why you are here, there are many hostile forces in this galaxy. We have kept the ones we felt that the galaxy couldn't handle at bay.
Vidar: We know feel you can handle a bit more.

As Odin says in the Hovamal:
"Praise no day 'til evening; no wife 'til on her pyre; no sword 'til tested;
no maid 'til bedded; no ice 'til crossed;
no ale 'til drunk."
