Indeed we do, gobucks. Much more so than most people realize. Yet we are confident that we can achieve "certainty" of knowledge about this world. It seems to me nothing could be further from the truth....
Thank you so much for your kind words!
The day science stops asking hard questions and challenging its own assumptions is the day we fall into Hari Seldon's scientific atrophy.
But unless and until we MEET and can physically incorporate the supernatural (using the classical definition "that which is above the physical world" which includes God or an Intelligent Designer) then the supernatural can not be a part of scientific inquiry.
