So they had to know about time. So time, the essence of time and that On large scale for seasons, for holidays, for festivals, for propitiation of deities and so forth, they had to keep track of it. And that's why in the caves in Lascaux that date back to the 40,000 BCE, they depict constellations. Orion, the hunter, Taurus, the bull, all these different constellations, they depict them there.

Now, partially that was because Netflix didn't exist back then, right? There was no TikTok. And so there wasn't much to do at night. And in fact, the more you were out at night, you probably increased your opportunity to be consumed by some predator, right? So you were more focused on being stationary, observing.

And as I said, we can do astronomy uniquely so amongst all the sciences with just the equipment we're born with. you know, measurements with our eyes with respect to landmarks to calculate patterns. And humans are exceptionally good at recognizing patterns, sometimes too good.

Yes. And the repetition of it over and passed down through generations. Before there was written language, there was pictography. There was the cave paintings and so forth. There was oral language and that was it. Written language is only 10,000 years old or something like that. So to store information, that meant it was a continuity between generations.

My great-great-great-great-grandfathers, elders, whatever, taught me that when the moon is in this constellation, the sun is in this constellation, we all should plant or we should harvest in other times. And so it was – we still do use – the rotation of the earth hasn't changed that much since this 40,000-year period, right? I mean the axis in which it rotates, that's a different story.

But the actual spin rate, the angular momentum of the Earth has not depreciably changed that much. And so the positions of these objects were of such importance that the ancients would use them for all these purposes. But there were so few things that changed position that they actually had names for them. They're called planets. So planet in Greek – It's like the word plane, like airplane.

It means something that moves or wanders. So when you name something, it means it's pretty different from the other things in which are not associated with that characteristic. So the planets, there were only five that they could see at that time up to Saturn. And they actually would associate those not only with astronomical events but events down on Earth. That's what connected the Earth.
