In 40k humanity is a middle age empire. The oldest empire is the Necrons, with the Eldar being younger, but the Tau have only been a space faring empire for a few centuries as opposed to humanity which has been in space for many millennia and is constantly battling against its own decay. They were the alien invaders snuffing out intelligent life wherever they found it and setting up human colonies to replace it, and now the empire is old, bloated, technologically stagnant, and in constant fear of being unable to defend itself from a number of crises that could lead to an exctinction level event for the species.

Star Wars is also a franchise that portrays humans as being an ancient race of space travelers. They're the most common intelligent species in the galaxy, can be found on most known planets, and collectively held the largest plurality of any interest group with in the senate. They've been a space faring species for so long that nobody even remembers what their real home planet was and it's essentially lost to time. It was earth. The space time phenomena that brought humans to the Star Wars galaxy sent them to thousands of years into past with space age technology.
