biology is probably the closest we can get to actual eldrich horror, realizing that everything you’ve taken as fact is complete nonsense and in reality all definitions are made up

like fucking hell, both animals and plants are compound organisms that billions of years ago swallowed some bacteria or whatever and it stuck around inside the cells and eventually atrophied into organelles!
And if that’s not bad enough, turns out we’re entirely codependent on bacteria in the stomach, to the point that in the span of a month you can become able to digest new things just because some specific bacteria multiplied a whole bunch, and those bacteria will then make you crave the stuff they can digest.
