Who are an alien term for people living on earth?

I don't think there is a Word for aliens living on Earth. I think they would just be called aliens.m

2nd Answer:

I THINK your question was "What do aliens call Earth people?"

There is no evidence to suggest that aliens (other than those coming across the borders of Mexico and Canada) have visited Earth. That being so, it is impossible to know what term an alien would use for Earthlings. An alien's speech probably would be nothing like ours . . . it could be clicks, stomach rumblings, or perhaps not even use sound! :-)
