Funny thing when reading that is as a human I read „crafted nervous system twice” like it would be done over a week or two.

We fail to imagine how much time takes to „craft a nervous system”.

Super scary how small are we in big scheme of things.

at one point I learned that it would only take a few hundred thousand years to evolve an eye, and time felt much deeper.

I think the fact that the sentence says we share the nervous system with jellyfish gives a good indication of that.
