Our ancestors outsourced digestion to fire. You evolved this way, and have a shorter digestive tract because of it.
Cooking meat kills bacteria that could make you sick, even deathly ill. Moreover, it preserves food such that it can be eaten for longer periods of time.
For millions of years, our paleo ancestors cooked meat. There is zero relationship with cooking your meat to eating a twinkie or a McNugget.
You evolved to have a big brain and make fire and use tools. Eating raw meat is like not doing algebra because primitive man in caves only knew to add/subtract/multiply/divide.
I'll eat a chunk of raw steak from time to time. If it's fresh off the beast it's clean. If it's older than a few hours, sear the outside edges.
I presume uncooked meat has more complex proteins, since they weren't broken up in fire. Good thing, bad thing? Probably neither.
