This make me wonder if flat-earth and other limiting cosmological views are mental shields against the realization that nothing matters except our peculiar existence.
The idea that nothing matters also doesn’t matter so you can go back to enjoying yourself and letting things matter without being a downer for nothing
generally limited world views regardless of the facts are a mental shield of people afraid of something. the problem is, the fear is so deep beneath the crust of hatred and other negative emotions that getting to it and working with it is often practically impossible
