Do you have the right to be an atheist?

[LostLocke]

I typed down "Atheist definition" onto google and i got this:
"a person who disbelieves or lacks belief in the existence of God or gods."

I typed down "god definition" onto google but i got religious definitions of god only but what i understood is this:
"the supreme being","a superhuman being".

Doesn't that make an superior alien race in some distant planet a "God"?
Like i said,we all believe in "God" we just don't know it yet.

Going by "a superhuman being" as a definition, then sure, a technologically superior alien race could be considered gods. Hell, even some of the larger dinosaurs could be considered superhuman, therefore they would be gods too.
That definition is so vague and all encompassing that it doesn't really have much use.

And no. Using that we don't believe in "God", we believe in "gods".
