"Why not?"

Because we are still learning a whole lot about how digestion works. It is not even close to being a completed science. It's all theory (theory not being a bad thing or just *mere speculation*). Theory is the endpoint of a scientific hypothesis, not *fact*.

Evolution is about as well understood as digestion is.

I would say that the way digestive system and how it functions, while we may not know EVERYTHING baout it, we pretty much understand the basics of how it works. On the other hand, we dont know if evolution actually happened, though science tells us it did. But we do know that people digest food.
