Why Are Humans Made of So Many Atoms?

If someone asked me why humans are made of so many atoms, I’d usually answer that it is “because you just need that many atoms to reach the level of complexity that a human body has.” However, that answer barely rephrases the initial question. If someone asked you, “Why do monkeys like bananas,” they would be pretty disappointed if you said that it is because they think bananas taste good. Schrödinger, of course, did a way better job answering the question.
