Humans couldn't figure things out yet, their cognitive abilities weren't fully developed yet so when things happened that they couldn't explain that frightened them, filled them with awe, made them extremely happy, whatever, they made up stories that eventually became gods. Yep, god isn't real. Well, except for mine, the chimp god. He's real. ;) lol!
Sounds like it's just a belt squealing. Either there's one loose or one has become "glazed" or overly smooth where it runs over the pulley. Another possibility is a pulley bearing/bushing is bad or going bad but this is less likely. None of these problems are very difficult or expensive to fix.
Wow! It's bad when a chimp knows more about human anatomy than a human! Of course it does!!! That's one of the first organs destroyed in an alcoholics body.
No difference, just semantics.
That's blankin' easy, chimpology! The worship of the ever lovin' chimp ;)
Why? I really can't think of one good reason. There are far far far more reasons not to than there are to believe.
No, we animals don't believe in god.
It has stunted growth in scientific endeavors for hundreds of years, promoted the belief that one race is better than another.
