What matters for Earth is, right, if you start the clock, when we could have had life at all, how long did it take life to get here, to form? About 100 million years, which is not that much time.
100 million years ago, the dinosaurs were here, right? So it's not that much time.
And we spent a lot of time being single-celled organisms, single cells.
Half a billion years, we started getting appendages, eyeballs and legs and locomotion.
But isn't it possible that there's civilizations that are way older than us that possess technology so advanced that our scientific instruments couldn't even detect it?
The reason why I think it's unlikely is we see sedimentary layers this is where we get the ancient fossils, okay? If there was an entire advanced civilization, I'm thinking they would leave something, if not their bones, they would leave some bits of their technology.
You're going to say, oh, there's a completely advanced civilization on Earth, but they vanished without a trace.
Because if they vanished without a trace, there's no hope of even getting evidence to support it.
If apocalyptic Earth and all of our cities submerged and then there's some civilization afterwards, something's going to stick out.
