ok Joe the same logic applies- that early animal had hair right? Every picture I have seen of early man from the evolution standpoint shows a very hairy man- covered with fur- so why would man lose the fur and then hunt animals for fun- this dispels survival of the fittest- it makes no logical sense.

First you have never seen photo of early man. Cameras didn't exist back then.
You have only seen artists renderings of them. And those artists renderings are based - ironically enough - on the work of evolutionary scientists who study the fossil records and have found evidence of hair in certain amounts on certain species. But it mostly conjecture, because hair and tissue don't survive long after death - just bones.
For the same reason, we don't know exactly when man's ancient ancestors started wearing either animal skins or vegetation fibers as clothing. Those materials would also rot and not leave fossil records. There are 2.5 million year old skeletons. There are no 2.5 million year old animal hides or human hair.
In the warm climate of central Africa, there wasn't much need for humans to have a lot of hair. They only got cold if temperatures dropped an unusual amount and/or they got wet in the rain.
However, at SOME point in our ancient past, humans began wearing clothing. Even hairy humans got cold as they moved further north. And once they did that, the amount of hair on their bodies became less and less important for survival. in essence, hair was much less necessary, it not outright unnecessary.
So less hairy humans were able to survive and pass on their less hairy traits. So, overall we became less hairy.
Interestingly, we retained hair on our heads, which is where much of your body heat escapes (heat rises). And we retained pubic hair because it provides a friction cushion that makes sex easier. Those traits continued to be passed on.
Whereas, hair on our backs was passed on a lot less.
