An Ancient Sumerian Myth or Reality?
Well-known (and highly controversial) Sumerian writings researcher, Zecharia Sitchin, stated that the gods of old Mesopotamia - the Anunnaki - were actually astronauts from the planet Nibiru.
Civilization of Sumer: existed from around 6,000BC to 3,000BC (pre-Babylonian times), in the current geographic location of Iraq.
Anunnaki (often also spelled Annunaki) - the dwellers of Nibiru; the word is translated into “those who from heaven to earth came”.
Anunnaki appear in the Babylonian creation myth, Enuma Elish. According to Sumerian myths, they were the creators of humankind.
However, this is a very controversial statement. Many researchers come to the conclusion that Anunnaki were at best attempting to turn already developed humans into their worshippers and the workforce in goldmines.
It is believed the Anunnaki were visiting Earth mainly for gold - although its further purpose for them is not clear. Sitchin hypothesized, they were using it to fix the ailing atmosphere on their planet. Other theory tells of the Anunnaki's need to deflect and reinforce the weak sunlight, when their planet Nibiru was beyond the farthest reaches of the Solar System.

Enuma Elish myth has about a thousand lines and is recorded in Old Babylonian on seven clay tablets, each holding between 115 and 170 lines of text (after Wikipedia).

Sitchin claims the Sumerians believed Nibiru to be a remote 12th planet (counting the Sun, Moon, and Pluto as planets) associated with the god Marduk.
According to Sitchin and his followers, the Mesopotamian sources present an evidence that the 12th Planet's orbital period is 3600 years. Size of Nibiru is estimated to be 4-6 times the size of Earth and itself possibly being brown dwarf-like, meaning it would be a very dense object, thus having extremely large force of gravity.
It's believed Nibiru moves on an elongated retrograde orbit and periodically visits our inner Solar System, causing strong perturbations in the gravitational balance among other planets.
Planet X was described by ancient cultures as of dark red appearance or looking like a cross in the sky.
Nibiru / Planet X theory is often connected with the hypothesis of our Sun's “dark twin” - Nemesis, which would be the other sun at opposite end of Nibiru's elliptical path, and around which the planet would also make its passage and turn back toward our Solar System.
Sitchin's interpretation of ancient Sumerian myths, left 6000 years ago on clay tablets, includes a story of once existing planet Tiamat in our Solar System, which was hit by Nibiru / Planet X (or some of its former moons) 4.7 billion years ago and broke up into smaller body, which we know today as... the Earth. The asteroid belt between Mars and Jupiter is said to be the other remains of that half-destroyed planet.

Scientists agree that the continents on Earth were connected at one time.
In fact, they list three ancient supercontinents: Rodinia - existed between 1100 and 750 million years ago, Pannotia - between 600 and 540 million years ago and Pangaea - up to about 237 million years ago.
According to the Sumerian myth believers, that could suggest the Earth came about as half a planet existing formerly.

The Mesopotamian texts speak of Planet's X periodic appearance as a predictable and observable event, which announced long-sustained rains causing flooding and the overall climate change.
According to Nibiru catastrophic story supporters, ancients saw the periodic nearing of the 12th Planet as a sign of great changes, upheavals and cataclysms.

There are plenty of hypotheses, as to what may happen in 2012 and soon after. One of them is Nibiru / Planet X passing Earth and possibly causing pole shift in 2012. Interestingly, together with the dangerous planet Nibiru passing Earth, the believers in Nibiru return in 2012 hypothesis state, that Aliens' return in 2012 is also likely.
The Planet X 2012 story believers state, that our current weather anomalies, in particular the global warming, are caused by the planet's gradual entry into the Solar System. Often they support their position by mentioning the recently observed atmosphere change also on Venus and Mars, among other planets.
