200-300 years isn't that old. There are plenty of buildings older than that all across Europe. There are businesses older than that. There are businesses and buildings that were older than that before the US even became a country. The *FALL* of the Roman empire was in ~500AD. It was a true empire even before 0AD, spanning across coastal Europe and northern Africa. It's height being ~100AD.
I'm sorry, the new world still has a few hundred years to go before we can even consider it old. It's not even a pre-teen by the standards. I mean we only discussed Europe. But the pyramids were older to the Romans than the Romans are to us.
But new world is getting pretty old now too.
