I am actually wondering about this now too. However a couple issues. Loki was left my Laufey to die because he is too small, Odin says so. So more likely his mother isn't terrain (human) but could've had the same form and been from another planet. We see many human looking people not of earth. Whoever it was- if she was human or mortal she died a very long time ago.
