Actually, Bahamut comes from ancient Sumerian legend. He is a multi-headed dragon that was killed by one of the Sumerian gods (forget who). Out of his mouths poured the Euphrates and Tiger rivers while his body became the land the first humans settled on (And my memory wants to call Bahamut a she, but I defer to the Final Fantasy version.).
