I think you are 24.

You're 24, or something close

You are probably over 100 but look to be around 24.

I'm giving you at least 99 years

I'm guessing around 370 years old.

Something like 19 maybe

Perhaps 14? You look like a student attending a festival, if not necessarily a human student....

I think you're about as old as the first story that was created revolving around you. How old is that? No one remembers.

You look like an artist's masterpiece that came to life.
It was pretty recent art, though....
So you're actually only a few months old!

You don't count yourself but you must be close to 210 by now
