It's just wierd that Tony meets a guy who can fly, summon lightning, crush part of his armor, and not be astounded.
OR Thor and Loki simply grew up at a normal rate and still did the things it says they did in the myths. Asgardians are extremely long lived but who's to say it takes them centuries to reach adult hood, they might reach adulthood around the same speed as humans.
Could be. But it's more likely that they grow at a much slower rate.
But even if you were right... in any case, the battle of Tonsberg at the beginning of the Thor movie takes place in 965. If we assume that from that point on the war between Asgardians and Jotuns probably still took a couple of years until Odin was victorious and if we keep in mind that Thor and Loki still were children after that victory, then during most of the Viking Age (which ended in the 11th century) there were no adult Thor and Loki.
