Does it count if your memory was wiped when incarnating on this planet? or do you mean the Aliens who came here without incarnating with a terran body? If the latter then there is no such thing and if they say so they are lieng. If you mean any off worlder, then yes what do you want to know? I am a Sirian, from the Sirius star system. Knowing how you Terrans think you wont believe me, but hey, at least pretend you do, that way we can both have a conversation.
