We, the human species, have evolved to survive with the essential abilities to notice patterns and be capable of remembering and articulating them and passing them on to future generations, with the result that our knowledge base has increased and been extremely useful in getting us where we are today. Unfortunately, running alongside this has been those who prefer to believe differently, rather than understanding why they do so. We have the wonderful ability to imagine absolutely anything and that story-telling is an absolutely crucial part of our development, not only of our fertile minds, but of group cohesion, is without question.
Just think of the huge developments in life and education there would be if knowledge about all the superstitions was given, with its correct interpretation, not an indoctrination or inculcation of 100~% faith belief. The fact that everything we think and do is our responsibility and cannot be blamed on any thing else. Unfortunately, this would remove from too many a support/comfort if done too suddenly, so it will probably take another several thousand years; during which time those who think they are going to be some spirits floating around in space or something will not be so!!!
Oh yes, and re the moon: physics will explain, I’m sure. Ask Prof Brian Cox, or an astro-physicist, or put a question on the science board. The apparent identical size is a result of natural law, not a mystic hand.
