The biochemistry might be quite similar, in fact, and especially for the simple life, because simple life starts really quickly.

on Earth.

So my take on this is that the universe is full of cyanobacteria, but as far as intelligent life, it takes more time.

So that can take different aspects.

We actually don't know what triggered the evolution to complexity on Earth.

That's still a big question mark.

That Cambrian revolution is really what took us towards what we are.

And in the meantime, there were the dinosaurs, et cetera.

The dinosaurs were wiped out.

So the evolution could have taken a completely different turn.

It's always, I would say, mass extinction that are going to drive what's the end game.

But...

Yeah, you take two planets and you change, you know, those asteroid impacts or those big geological events that wipe out like 90% of life at any time.

The thing that seemed to be interesting, there are two things.

The first one is where you are located on our galaxy matters a lot.

We actually are in the habitable zone of our galaxy.

And if you are too close to the center, then it's a lot denser.

And remember, we have the Oort cloud around our solar system.

And if you are in the region of the galaxy that's too populated, then you are going to run interaction, gravitational interaction with all these stars.

And since it's more dense, you will have more of the comets that are living in the Oort cloud being ejected from the Oort cloud and
