My brain is a stand alone version of the most complex thing in the known universe.
What does that even mean? What are you considering to be "the most complex thing in the universe"?
Humanity more or less classes the brain as a computer
Ahh, you've taken an analogy literally. The brain (human or otherwise) merely has similar capabilities or qualities to that of a computer. One of these the ability to process information.
and lots of these computers independently and through a myriad of experiences called life come to the conclusion that there is a God. More people - brains - computers come to the answer 'God' than those that come to the answer 'no God'.
Just because there are a lot of people that BELIEVE something doesn't make it so. At one time A LOT of people believed in witchcraft in some form or another (they either believed themselves witches or believed them worthy of burning at the stake). Also alchemy. What say you to those claims?
My question is why isn't the human belief in God classed as scientific?
Define scientific and we can tell you precisely why human beliefs are antithetical to science.
When the most powerful computer network in the known universe comes to the answer 'God'?
The most powerful computer network is not the human brain. Can your brain transfer even a single math problem to someone across the world? I can
with an actual computer. I can even relay that information to someone that doesn't speak my language. Can your brain do that? Can your brain perform mathematic algorithms in a split second?
You put far too much stock into the human brain when even a home desktop computer, or even my smart phone, is far more efficient, yet my computer is atheist.
Define some of your terms then this discussion can move along at a better pace.
