There's so many things you can make with milk it's really cool. In general all the ways people found to store and use food items that would otherwise spoil too fast
But I mean, almost everything we eat is the result of the metabolism of another living thing. Either directly or otherwise.
Plants, animals, fish, kelp, mushrooms, milk, kimchi, apples, oranges, tea, kombucha, beer etc… even if were to only eat food synthesized from oil byproducts or coal, it would be processing the product of something that once lived.

Eating germ poop is basically the human experience
