When was starwars

Hi guys, I think I know when starwars was.

In the Ewok movie we can see horses.

You may just dismiss this, however it brings up important facts. Horses evolved 5 million years ago ( 5,000,000) so that gives us a rough time.

Assuming that the starwars galaxy is the Andromeda galaxy we can find that if the ship transporting the animals was the same speed as the melenium falcon it could get to earth in 50,000,000,000 years.

If these two facts are true than that means that starwars would have existed 599,995,000,000 years ago.
