You mean Bishop Usser who dated the world at 4004 years old?

Not exactly. I believed he dated the Creation to 4004 BC, which would make the world a little over 6000 years old.

To be exact, he dated the Creation of Adam at 4004 BC. That is by no means the same thing as the age either of the Planet, nor of the various animals or plants or whatevers, including evolved humanoids not descended from Adam, even if some might be homo sapiens.

OTOH, Ussher was slightly off. We now know the true date for Adam's creation to be 3971 BC, the main dispute is between August 11, and mid-September, of that year.
