[General Science Fiction] Why do alien species name themselves after their home planets?

Sure, if humans meet aliens from Mars, *we* call *them* "Martian." And if aliens visited Earth and met us, *they'd* call *us* "Earthlings" or "Terrans." But we call ourselves "Humans" while our planet is called "Earth."

So why do aliens name their **own** species after their planet? Wouldn't the names have different origins?

They might have a name for themselves in their own language, but when speaking in a foreign tongue (especially of the other speakers lack the necessary vocal appendages), it's important to have clear lines of communication, similar to Terrans/Terra thing.
