The last section captures what I've tried to say in my own (not currently online) writing on the subject of life, existence, and purpose/meaning.
> As far as we know, we and our societies take the prize for being the most complex structures the universe has yet evolved.
This is where I end up in a lot of my own musings on the subject. Another point I typically make is that we KNOW that the immense diversity and complexity that exists on Earth will end in the future, unless some intelligence is able to spread life outside of Earth.
Personally, I think that one of the most important human activities should be actively trying to seed other nebula, stars, and planets with archaic life, since this increases the overall probability that life will continue to evolve somewhere, even if humans fail to expand beyond Earth.
We could be parallelizing the process of life across worlds and creating potential for other interesting life to evolve to solve the unique problems of other parts of the universe. By spreading life from Earth, we also increase the likelihood that future intelligence could find evidence of our (and each others) existence, which would be _very_ interesting (for them), and could help them get through the difficulties we face now.
I'm not sure how you resolve the opening of "we're just here to fart around / dance" nihilism with what you mention at the end about how Earth, life, and humans being the most complex and interesting thing going in the universe, but I like the style/format, and I'm definitely going to give this a longer read later. Thanks for sharing!
