People love symmetrical patterns and proper ratios our brains seem to be fine tuned to noticing and examining them for information and correlation. Theres a billion theories as to why, nobody really knows. Me I personally think that the universe in totality is somewhat conscious and has a deep appreciation for the fundimental abstract truths baked into the concepts of symmetry and higher levels of complexity forming beautiful tapestries of order. As we are higher complexity beings spawned from the universe we inherit this appreciation that lead to the creation of life and our awareness in the first place.
