That's the million dollar question, isn't it?

The closest we have to a timeline concerning the existence of Ghouls involves the history of the Washuu Clan. And even that is simply a matter of guesswork, based on historical details. Since they were firmly established as a prominent Clan by the 19th Century, that means their ancestors had to have immigrated to Japan prior to the 17th Century.

There's records of trade and immigration between the Middle East and Japan as far back at the 14th Century. So we have a period of 300 years where the Washuu Clan ancestors came to Japan. So Ghouls have to have existed for a 1000 years or more, to have firmly established bloodlines by the 14th century.
