There are actually thousands of scriptures from around the ancient world about unicorns and fairies.
The dominant religions in Europe before Christianity took over were full of fairies. As well as other ancient religions around the world with almost identical myths (although different NAMES for what were essentially fairies).
The same case that is made for the existence of god, could be made for the existence of fairies.
And if god is in reference only to our personal needs, and only dwells within us? Than it's not god, it's just some psychological construct.
Frankly, I don't think much of what u r referring to is myth. I call it legend. Most stories are embedded in some form of fact, something that happened and a story emerges from there. There probably were some kind of horses with one horn on their head which is how the stories may have started. There are fossils of one horned horses actually. Even trolls and leprechauns may have an actual link to a real people which was shown on the discovery channel. A very short species.
Not sure what u mean by only our personnel needs and something within us. I would't agree that if that is all it is then its merely psychological. But to me, "god" is something that is used to describe what is within all living things and even non-living things, that connects everything to itself and manifests in all living things. Is everything and nothing.
I don't think the material world is real at all, but an illusion.
And I think nature is far more interesting than most of you give it credit for, and doesn't have to make sense to us, or be measured by us or dissected by us to be.
I think a connection to something allows u to understand it in a way mere measurements alone cannot. I can dissect ur brain, but that tells me nothing of how well you spoke English or your mathematical skill. When I am connected to u, get to know u then I learn these things. Scientists in the past failed to see how clever great apes were by mere measurements. It was three women who dared to named their apes and connect to them that learned and showed everyone how amazing they really were.
People of the past may not have the sophisticated tools we have today, the computers and fancy gizmos that allow such precise measurements. But they were connected to nature in a way many of us fail today.
Connecting allows for intuitive truth, which is why Einstein rightly understood SR even though no one understood how and why he would come up with it.
