The problem is that we no longer kill animals, drag them home, and eat them immediately. The meat you buy at the supermarket is weeks, sometimes months old and has spent time in factories and on trucks getting to the place you buy it. So in all that time there are LOTS of opportunities for bacteria to collect and grow on the meat, so you need to cook it to make sure you kill all that bacteria that would otherwise make you sick.
In addition, cooking meat makes the nutrients within it more bioavailable (more efficient nutrition) as well as simply tasting better, so there's really no good reason not to cook meat except in the most desperate of situations.
