Question: How many thousands of year would you to travel back in time to go back to 3rd_millennium_BC!?
Best Answer - Chosen by Asker:

Dear Neptunek,

We live in the third millennium AD (anno domini or year of the Lord) so to return to the third millennium BC (before Christ or BCE, before the common era to non-Christians) you would have to travel six thousand years!. That would get you to the very beginning of the 3,000 BC period!.
