Actually, I think that one's just poor word choice - "our" is likely meant as in "the Shepard family". He does say it's his dad's 'gi-taa'. Canonically, Colonist Shepard's parents most likely were born on Earth, given the timeframe.

Either way, it's small potatoes next to things like the Reaper homeworld, cross-species offspring, Evil Zombie Clones, Vigil's reappearance... (etc.)
