Who was the "First God" of the Norse People?

Buri was the very first Norse God. He’s the son of the giant frosty cow Audumbla, who apparently uncovered him by licking through the ice.

His name means ‘The Producer’. Being the first God, he didn’t waste any time in creating more, starting with Bor. After that came Odin and the beginnings of Norse Mythology.

Norse mythology is the body of myths of the North Germanic peoples, stemming from Norse paganism and continuing after the Christianization of Scandinavia, and into the Scandinavian folklore of the modern period. The northernmost extension of Germanic mythology, Norse mythology consists of tales of various deities, beings, and heroes derived from numerous sources from both before and after the pagan period, including medieval manuscripts, archaeological representations, and folk tradition.
