Ring around the planet
It’s amazing that astronomers can look at the earth as it is now and know how the planet appeared 466 million years ago. A series of meteor markings near the equator, and what is being seen in earth’s near space region, is evidence that earth once had a ring.
If we looked up at the stars so many millions of years ago, we would have had a very different view. The moon and the planets and the stars and the sun would have looked much the same as they do today. But the Earth itself would have been encircled with a ring system similar to the ones around Jupiter, Saturn, Uranus, and Neptune.
