Actually the matter that makes up our bodies has been around since the start of the universe, so all of us are much older than Japan

but here's the thing, japan's land is also made out of matter
so we're technically the same age

Fair point
But I believe it is referring to the formation of the first organized civilizations in Japan

And my formation was in the 2000's
so fair point

But civilization is merely an idea
Human beings are an object

i meant my object was constructed in the 2000's

Same
