imagine you're an organic cell in human body with little mind (consciousness) on your own (at least you generate your own electromagnetic field that interacts with other cells), you live your life, do your thing, divide, die off, divide again, etc... - would you ever know you're a part of human body capable of many things beyond your scope of functionality?
concepts of God are primitive and made that way for primitive minds - which is not bad, imagine level of crimes we might have on the streets w/o so much religious influence over those minds or maybe we would be far more advanced, who knows.
we might as well be micro parts of something bigger and being inside of it we'll never see externally whole picture. we'll never know beyond our reach of understanding and experience of our existence. sober scientific approach without bigotry with get us far.
