I mean, this was a pre-ceramic culture, so there were no artifacts to find.

So they just moved on.

It wasn't until Dr. Ruth Shady in the 80s and 90s

actually put research in and figured out, hey, this is older than everything else we found because they just overlooked it.

There were no artifacts.

They were just like, we're going to move on.

When you say no artifacts, that seems weird to me because why would you make these immense structures and not have a bowl to put rice in, right?

A lot of animal skins and the weaving –

So these cultures, what they found is – so that's a little further inland.

They had a sister site on the coast.

And so what they would do – the only agriculture they would grow was cotton.

That cotton, they would trade with the people on the coast so they could make nets and fish with it.

The fish they would bring back, they would give back to those people who made the cotton for them.

So it was this weird interplay and –

The other unique thing about this time period is there was no evidence of warfare for 1,000 years.

Nobody was fighting each other.

It was very just everybody, no weapons, no anything like that.

No weapons?

No weapons for 1,000 years.

That seems insane.
