In Avengers film released this year,

Loki when he first exits out of the Tesseract and enters Earth realm, the S.H.I.E.L.D operatives open fire on him and we see bullets just basically bouncing off him like he is impervious or something to our weapons.

Does this mean that Asguardians are similarly god-like ala Superman or was this the direct result of him having the scepter that gave him some sort of a shield (or some other technological advanced defense)?
