As Q’uo says, Sitchin work is very "distorted". His claims were that the Anunnaki were big humanoid aliens from a distant planet called Nibiru, located in the Solar system beyond Pluto. And that they created Homo Sapiens by genetic engineering of the Homo Erectus.
Not only his claims contradict what Ra said about the Anaks, but Sitchin was proven wrong by many scholars. Indeed, his translations of Sumerian texts are very inaccurate, and absolutely no cuneiform text ever mentions the Anunnaki came from Nibiru. Also, Nibiru in Sumerian texts is the same planet as Marduk in later Babylonian texts which is today known as... Jupiter.
