"Extra-terrestrial" literally means "inhabitant from extra land". This indicates to me that any "aliens" are likely not from space, but from areas of the Earth
You are mistaken. The prefix "extra-" means "outside" or "beyond". So extraterrestrial refers to a being from outside earth.
Yes, I could be wrong. My interpretation is that “outside Earth” is “outside known Earth”. My point was that it is still outside Earth if it is on the planet, but in lands where humans cannot go for some reason.
