And I wholeheartedly agree that we don't know everything. The problem there is that the gaps in our knowledge are vulnerable to being filled in by imagination, flights of fancy and sheer speculation. Anything that doesn't require evidence. In the realm of religion, we call that filling-in "the God Of The Gaps," whereby anything you can't instantly explain via science is "explained" via mysticism (often expressed in obscure ways not intended to be understood by we non-cognoscenti) or resort to the unexplainable supernatural.

Near-death experiences and precognition are prime areas for this distortion of science to prevail...
