Zecharia Sitchin's translation and
reconstruction of the autobiography of the Sumerian god Enki, called:
"The Lost Book of Enki (2001)", based upon his translation
of the Sumerian clay tablets. Part of the story tells about Alalu
(possibly known as "Cronus" in Greek mythology); the
ruthless former king of the planet Nibiru, who fled to planet Earth ("Ki" in Sumerian) after he was
overthrown by Anu (became the new king). Because of the necessary flight through the asteroid belt
in order to reach Earth, it was a dangerous endeavour that had never tried before by the Niburians.
Probably he preferred to take this risk instead of being captured by king Anu, and also because his research
on Earth would be a great merit to the inhabitants of Nibiru he hoped
that he would be able to reclaim Nibiru in the future. He was
apparently the first inhabitant of Nibiru who came to Earth around
500,000 years ago. One hoped that on Earth there would be found gold
in abundance, what could be used to repair the atmosphere of their
dying planet Nibiru, but this was rather disappointing and most of
the gold would be deep inside the Earth, which was hard work to get
it out. Later Anu's sons Enki (Ea) and Enlil arrived on Earth with
their crew to mine the gold.
Later Alalu would have fought again with Anu for the authority of the planet Nibiru, which happened this time in the form of an unarmed hand-to-hand wrestling match. Alalu lost the match however and in his frustration he castrated Anu. (Remarkable similarity with Greek mythology were Uranus was castrated by Cronus.) Because of this crime he was punished severely and was banned to the planet Mars. However it was not the intention to kill him he however shortly died on Mars. Possibly because of the awareness that he his punishment was rather too severe and the fact that his life anyway was a great merit for the inhabitants of the planet Nibiru, he was buried with respect inside a huge cave wherein the face of Alalu was carved. By the means of this the cave became a memorial for his heroic journey to the planet Earth, where it seemed that he looked from the planet Mars to the planet Earth. This story reminds one, of course, to the alleged "Face on Mars" from the Cydonia region on Mars, and coincidence or not; the Greek goddess Cydonia is the goddess of heroic endeavour.
Colonists of Mars called the Igigi (see the chapter: "the Sons of God and the Daughters of Men") would have used this specific area of Mars as a temporary mid station for the gold transport from Earth to Mars. This could be why there are could be those piramid-like formations and other possible structures which are situated nearby the "Face".
