What does consciousness tell us about the unknown, namely God?

Science tells us the physiology of consciousness. The physiology of brain activity in particular has been extensively mapped and can even be traced with medical equipment due to natural electrical impulses that the brain generates. However, human thoughts have never been proven or mapped. Human dreams experienced during r.e.m sleep have also never been proven or mapped. We see manifestations of thoughts, namely through human activity, however “thoughts” and “dreams” are unproven phenomena that each person that is living and breathing either has or doesn’t have. In the philosopher Rene Descartes’ “Dream Hypothesis,” he challenges any person to prove at any given point in time whether he is asleep or awake.” To paraphrase his assertions, he says that he has identical sensations while he is dreaming to when he is awake, and in many instances he is not able to tell the difference. What can science tell us about the unprovability of human thoughts? What is the essence of a human thought, and what are the consequences of thought in relation to a higher being? In the Bible, which was written more than 2000 years ago, we see the thoughts and opinions of its writers in relation to mankind and God. In Isaiah 55:8, we see an acknowledgement of the mystery of mankind in relation to God and the universe; “For my thoughts are not your thoughts, neither are your ways my ways, saith the LORD. For as the heavens are higher than the earth, so are my ways.” And in Psalms 139:14, we see the Psalmist, King David, comment on the complexity of the human form. “I will praise thee; for I am fearfully and wonderfully made: marvelous are thy works; and that my soul knoweth right well.” What do the unknown processes of human thought tell us about the potential existence of a higher power?
