since ancient times,people (in all parts of the world) have told myths and stories, or legends, to explain things they did not understand. Early Thai,for example, explained the cause of thunder and lightning with this story:a beautiful girl named Mekhala had a crystal ball. A demon named Ramasun had an axe.Ramasun wanted Mekhala's crystal ball but she flew up into the sky to escape from him.Ramasun chased her,while her crytal ball flashed light and sparkled.This flashing angered Ramasun.So he thew his axe at her. The flash of the crystal ball was said to be lightning and the throwing of the axe was said to be thunder.
