One of the surveyor's tool is a stick with a wheel on it. So the wheel's a circle. So you got so many multiples, they just counted. And that's how, so we confuse a lot of things.

Exactly, right? They walked all over. So you don't have to always posit supernatural explanations for things. The answer is simply, we don't know. I certainly don't know how Stonehenge was built, nor do I know how the pyramids were built. But it's not, you would have to convince me that it was built by some other means other than people and the tools that were available to them. Likewise.

I don't remember how we got on this. So we were marching through.

Then it was Copernicus who had ideas but couldn't prove them. He had no data to substantiate the Copernican or sun-centered model of the universe, which is Also, by the way, you know, almost everything in science is wrong, right? Copernicus is wrong. The sun is not the center of the solar system, right?

So then you come up to – after him, Kepler discovered the laws of the elliptical motion of planets and their patterns that we still use. We discovered an exoplanet. My colleague David Kipping, I want to introduce you to. He has discovered exomoons.

These are moons around other planets, some of which are in the habitable zone of their host star and some of them have sun-like stars and are earth-sized planets. It's incredible. There could be, as I said, a link between life evolving on Earth due to the moon on our planet. So too, on an exoplanet, it could require an exomoon, which he's discovered or thinks he has.

He's actually very cautious and hasn't said it explicitly. So Kepler's laws underpin all those discoveries, even to this day, 400 years later. Then Galileo, immediately afterwards with the telescope, phases of Venus that only occur if the Earth is not the center of the solar system. The rings of Saturn, he had notions about those. He accidentally discovered the planet Neptune. It's amazing.
