Stuff like this tends to amuse me, as they always look at it from a linear progression of time.

That the universe just is this way.

That maybe the patterns which appear like the neural connections in the human brain mean that the human brain was the result of a pattern inherent to the universe.

Simulation theory offers a refreshing potential reversal of cause and effect.

Maybe the reason the universe looks a bit like a human brain's neural pattern or a giant neural network is because the version of it we see around us has been procedurally generated by a neural network which arose from modeling the neural patterns of an original set of humans.

The assumption that the beginning of our local universe was the beginning of everything, and thus that humans are uniquely local, seriously constrains the ways in which we consider how correlations like this might fit together.
