Can people eat raw meat safely?

I am thinking of going on a all raw diet, I already eat organic free range chicken eggs. I know you can eat sushi etc. But if I can find a source that I can buy raw free range organic BEEF, would that be very deadly? after all, dont animals eat raw meat? And when we were cavemen, didnt we do it then? Please no immature answers. I am asking this because I want to be more healthy without all the chemicals and get the highest grade proteins there is. Because cooking anything can degrade the food. Thanks.
