cuz the when the desert was formed their was a huge fight between the the lord of desert n the lord of greenery. lord of desert hated greenery so wanted no rains so that everything in that place goes dead but greenery wanted to spread its wings every where !
but sadly in the end lord of greenery lost cuz lord of desert had more powerful weapons than him ! and hence it stopped raining in deserts !
ah i know not that creative

but i tried

how come i never meet u ?
