Earth, our home. How many myths and stories are there in ancient and modern times, both at home and abroad? Pangu created the sky, Nuwa created humans, the gods of Olympus, the Nordic giants... Why do they only exist in yellowed books and oral legends? Is it a magnificent crystallization of imagination, or... A distorted reflection of some forgotten reality? Perhaps, it's not that the time is too far away to be tested, it's just that... The time has not yet come.
