Hi, Max.
I'll let others handle the exact nutritional benefits or nonbenefits of raw food. Right now I'll just reply to one point:
Humans have been evolutionarily selected for to eat these types of food. More precisely human ancestors were selected for to eat these types of foods. This time period is much longer than the time we have been eating cooked and other "dead" foods.
The evolutionary history of our species may give us some insight in regards to optimum diet, but it isn't going to give us any definite rules. What is important is what selective forces have acted in the most recent past, and whether it has been sufficient to change the earlier diet. Evolution can be pretty quick.
Although examining our closest relatives (and chimpanzees, by the way, do include meat in their diet when they get a chance) will give some insight, the only way to determine the optimum diet for humans will be to do research on actual living humans, by finding correlations between health indicators and diet.
In the end, evolution cannot tell us
what the best diet for humans is; at most, it can tell us
why a particular diet is optimum once we figure out what it is.
