ELI5: why are humans the only ones that require cooked food/water when most other species can eat/drink and be merry?

Cooked food “preprocesses” it for our digestive system allowing more of the nutrients to be extracted, thereby reducing the amount we have to eat and getting more benefit from what we do eat. It’s likely this contributed to the increased size of human brains vs what existed prior to cooking. This likely started over a million years ago. You could say cooking food was required for humans to evolve to what we are now.
