There is a noun meaning "another place." So if you're not here, you can only be there.
This very general term names a place apart from here, but it has many uses. It can mean “at that point or place,” as in "It is there that the argument starts to seem silly.” People say "There, there" to console someone who is sad. This word describes a situation too, as in "There is a problem" or "There's no place like home." If you're pointing something out that's hard to see, you'll say "There! Right there!"
