Millennium(time, not structure)

Oh, hi there, the creator is here. I am PRETENDING that i lived for 2020 years. Funny, eh? I lived for 2 MILLENNIUMS. What IS a millennium? My lesson here. A millennium is a time for 1000 years. Or, 10 centuries. 21 centuries, so 2.1 millenniums(since 1 A.D.) and that is a lot of time.
