Reality, what is it? It's the zone in which human comprehension exists. Extend the low side 'till completely flat lines in the horizontal. becoming zero, now extend the high side 'till it completely flat lines in the vertical, again becoming zero. Now swing the two zeros around in an arc until they touch (zero is zero regardless) forming a complete circle. Reality is the small section of that circle that is human comprehension. Is there anything on the outside of that? The only answer is "we don't know" and not only that, we are not likely to know, and even if we did, what good would it do us anyway. So anyone who says they have proof of the existence of the supernatural is either a liar, or a shyster or both. We don't know enough about reality yet, so let's just concentrate on that.
