early man vs KL man

Early Man had to do a lot more than KL because Kl can just get meat from a store, and early man had to hunt for meat. We can just get water in a bottle at the store and early man had to dig a hole in the ground or go to a river to get water. we have almost destroyed the earth (NOt really) and not helped the earth. But early man made no difference to the earth. we have a lot more tools than early man had. yet they where more successful then us. For shelter we had more bigger and better shelters. but they where more creative in shelters than us.
