The earliest trees evolved around 400 million years ago.
The ancestors of bacteria were unicellular microorganisms that were the first forms of life to appear on Earth, about 4 billion years ago.[23] For about 3 billion years, most organisms were microscopic, and bacteria and archaea were the dominant forms of life.




The moon is currently drifting away from the Earth. Eventually, that will make total eclipses impossible, so enjoy them while they last.
Fast forward a few billion years, and the Sun begins to swell up, engulfing the closest planets. At some point, the atmosphere of the Sun could begin to cause drag on the Moon, slowing it down. If so, the Moon begins to crash down on Earth. Once it reaches the Roche limit, it gets shredded into kwazillion bits, and the Earth will have rings, just like Saturn.
