One is obviously made-up by ancient peoples who knew fuck-all about the world, but insists it’s eternal truth beyond debate. Even the parts that contradict the other parts.
The other is an openly hypothetical idea based on what we expect is just beyond our current capabilities… and it relies on that we’re-just-atoms materialism.
English is an endless deluge of that experience, because our orthography is bullshit. People have tried to fix it. Their clever rules were partly adopted and became even more exceptions and special cases.
Both beliefs are fine, but please realize the hypocrisy (sh.itjust.works)
