How do we know what we know?

     To us, it seems like a simple enough question, ‘how do we know what we know?’  But how about for the first ever people?  It is a very difficult concept to understand, but I suppose that the first people began to make up “facts” which we simply built upon.  There is no doubt that we know far more than those before us, it is evident through our culture and technology.  Colors, for example.  They could realize that all of these “things” had a certain quality to them, but had no word for it, or way to express it.  The first spoken language was most likely a series of grunts, or noises we would not normally see as a language.    However, it was this way that they could describe these qualities, or colors.

     From then on, it became far more organized, and taught in a way that people could understand.  By pointing to all of these objects which share the same quality, it could be inferred that the noise they made when pointing to these things was describing that quality.
