At The Start...

At the start, Fig created the world. And because creators always seem to be men, Fig was a woman, and yes, she did have big boobs, because big boobs are better than small boobs. Fig got a bit lonely wandering around creating things, so she created Mango from her toenails. Mango was also a woman, and because Fig had big boobs and was generally big and beautiful and fruitful, Mango was very small and sat on Fig's shoulder, and told her what Fig couldn't see because she was too high up.
Fig and Mango created trees and named them after each other and just generally fell in love, which proves that Sapphites come in peace. Then Mango wanted a baby, so Fig made a baby out of poinsettia petals, and it was a boy and they called him Jared.
Mango and Jared lived in a cave while Fig went off creating things, and when Fig got back Jared was a man and he wanted a wife. So Fig made him a wife called Jedda from a scrap of silk which had fallen off of her conveniently placed toga. Jedda and Jared went off and had twelve children, and taught them about the goddesses who lived in the caves up the mountain.
Fig was sad because she didn't fit into Mango's cave, and Mango wouldn't move away from her family, who she watched over with her magic telescope :). So Fig went off and created more things for the world, and when she got back twenty years had passed and Jared was an old man. However his eldest son Dave had listened to his father's tales about the goddesses and wanted a wife, since he had an inkling that it might not be quite right to sleep with one of his thirteen sisters. So Dave went off up the mountain and prostrated himself before Mango's cave, and he prayed for a wife.
Mango came out of her cave and kicked Dave's butt down the mountain. She told him that the only way to make his race strong was to sleep with his sisters. So Dave did, and that is how humanity came about.

This proves that Sapphites are good creators, but not so good in the reproduction line of things. Since Dave's family ended up Neanderthals and died out at the end of the Ice Age. And they all looked really, really similar...
