ya Aliens exist ya
 

As the Earth is a spaceship itself, travelling through space at nearly 70,000 per hour, I'd say we humans are space aliens. Therefore, there is no such thing as space aliens. Just migrants or visitors from another planet. Calling visitors from another planet aliens is racist.

I'm sure by monitoring us they figured out that we would call them that since on Earth we judge by location and appearance thinking whatever race we belong to is the right one and everyone else is out to get us or use us.

Aliens literally means "foreigners", so, no we are not aliens, at least not until we visit some other planet. That may happen someday if we don't manage to destroy ourselves before that.

Migrants or visitors from another planet would be foreign to us so yes, they would be "aliens" and since they came from outer space they would be "Space Aliens"

How is "aliens" racist? A tourist visiting the U.S. from France would be an alien. A U.S. visitor to France would also be an alien. Race has absolutely nothing to do with whether somebody is an alien or not.

There should be no stigma about the word alien.
