why is the lack of "fur" positive Progression for humans?

or it could be because God used intelligent disign and made us that way

besides the fact if we evolved then we start reevolving in the womb am i right but funny thing we have little to no hair and if we evolved next generations would have less and less hair but that isn't true look at history dark ages long hair then we cut it hippies long hair the we cut it new age long hair it is a stretch to say that we evolved out of fur not historical finds show any evidence of excess body hair in previous years

ok the last one was a typo it was supposed to say no historical evidence so im saying never was a man a monkey man was man and monkey was monkey there may have been a cross breed im not denying that i was saying hypotheticaly in the womb a person starts in the "fish stage" and progresses to a human by the third trimester but i don't think that i think it is a human from conception

i meant if i know we don't eveolve in the womb we never evolved period
