Throughout Human history, it seems that there is a reoccurring theme which starts with our solipsistic arrogance, where we assume that we are at the center and the purpose of it all, only to discover that we are indeed, only a tiny fraction of a much grander and much larger reality.
The geocentric model of the cosmos was replaced with the heliocentric one, only to be latter replaced with a galactic one, shortly thereafter being replaced by our current multi galactic understanding which has no "center", and now there is growing evidence that there was a universe prior to this one as is evidenced by gravitational anomalies in the cosmic microwave background and as predicted by inflationary theory. This is all possible and evidenced without mentioning the possibility of a single infinite universe or the highly speculative possibility of a multi-verse, as defined by the many worlds interpretation of quantum mechanics or other theories such as cyclic cosmology.https://arxiv.org/abs/1808.01740
All of this seems to suggest, that humans are not special, and that any reality that can exist does exist, and because it is self-evident that humans are possible we must therefore exist.
I want to take that above possibility as an assumption, if you don't think this is true that is fine, I'm not forcing you to, but for the sake of debate this should be an assumption that this is true.
What are the philosophical implications of an ultimate infinite reality that is like this, where whatever is possible does exist somewhere?
At some point in the distant past, the universe went through a phase of cosmic inflation,
Stars formed, planets coalesced, and on at least one of them life took root.
Through a long process of evolution this life developed into the human race.
Humans conquered fire, built complex societies and advanced technology .
All of that so we can argue about nothing.
