At the risk of the wrath of the rest of the hubbers, I'll tell you what I think. I believe it is quite possible that everything we imagine has existed, or will do so, at some point. Myths could, quite possibly, have a strong basis in fact.
Myths, legends and folktales, create and submit your own or delve deeper to find out origins and context of the great spiritual unknown. Science is one form of tool to manifest from the spiritual unknown into our ego self to be known. For example, some may think love or God is a myth, yet when one dose tap into the high energy of love or feels closer to God, is when one finds Science technology is indistinguishable from magic.
From being an artist, I find most good art is spiritual, even better is discovering a Myth or sacred explanation of how the world and humankind came to be in their present in somewhat different ways, in a very broad sense, or refer to any traditional story in society. Myth is usually true account of the remote past and how the world gained its current form.
I do not belong to any group for it limits my thinking. Inspire to a mystic approach, practices, or a reference to a mystery, mystic studies of the great spiritual knowns. A person, moving slowly with grace, into our spiritual age and closer to God.
