On this planet, it took over three billion years to go from a single cell life to anything more complex than a single cell. And then another half a billion years or so to go from the multisellular things to a civilization. So it's it's 3 and 12 to 4 billion years. It's a third of the age of the universe.
If you look at the history of life on Earth, then you see that life began pretty much as soon as it could here on Earth. We have evidence there was life 3.8 billion years ago, something like that. And the earth's four and a half billion years old. So pretty much pretty quick in geological time you get life.
But then if you talk about advanced life, complex life, multisellular life, then there's no evidence at all beyond back beyond a billion years actually really in the fossil record. 650 million years ago or something you start seeing the first evidence of complex creatures.
That's an unbroken chain of life on a little piece of rock in a violent universe.
