Sumer may be the first civilization in this world,
first appearing in Southern Mesopotamia between the Tigris and Euphrates
rivers around 6,000 BCE, in the area now known as Iraq
and also included parts of Syria and Turkey.
The Sumerians called themselves Sag-gi-ga, "The Black Headed Ones"
After their civilization was already a thousand years old
( around 2,300 BCE) there is written accounts of creation,
paradise and a flood that destroyed the world.

The Sumerian's: Nibiru was the twelfth member in the solar system
(which includes 10 planets, the Sun and the Moon).
Its catastrophic collision with Tiamat, a planet that was between Mars and Jupiter,
formed the planet Earth, the asteroid belt and the Moon.

Nibiru means "Planet of the Crossing".
Many predict a return date of Nibiru passing Earth
coinciding with the Winter Solstice of 2012;
specifically at 11.11 UT, 21st December, 2012

Today's modern UFO's and Alien Contacts being reported have a strong similarity to the Ancient descriptions of the "anunnaki" Android Beings. When we look at the descriptions of our modern "grey alien", we can clearly see that they do not look like us, or the anunnaki. Rather, they look like the ancient humanoid depictions of Figurines. The majority of Abduction cases usually have a similar story to them in that the Aliens abducting them will perform medical examination and sometimes experiments having to do with human reproduction.

The Sumerian Culture, which dates back to 6,000 BC, is the oldest known culture on Earth. Even today we still use the same Mathematical system, Calendar, and Time as they created it so long ago. Since we have the evidence left over today, 6,000 years later, we can see similarities between what they had then, and what we have now.

The Sumerians describe Planet X as being very far from Earth at times, (roughly 30,000,000,000) miles away at it's farthest point from us in orbit. This would make it rather difficult to travel back and forth between the two planets if separated by so much of a distance.

The Sumerians had amazing knowledge of the solar system, and of their GODS coming down to Earth. They also tell of another being that they described in our terms as "Android Beings". The Sumerians tell us that the anunnaki had "helpers" that often performed such tasks as flying their craft , or helping with miscellaneous needs. The Sumerians directly explain that these "Helpers" we not alive, but acted as so...

Not only did they make figurines of the visitors, they also wrote down in Cuneiform text (on stone) what took place during the encounters with these "Android Beings". There are many stories where Emissaries of GOD helped out in one way or another.

Is it possible that the Greys were created by the anunnaki as "Watchers" to oversee their experiments here on earth? If the anunnaki are the GODS spoken about in all ancient texts and even the Modern Bible, then it is possible that they could have also created an "Android Race" aside from creating humans.

Maintaining the idea that the anunnaki really do exist on Nibiru (planet X), and they created man using Genetic Engineering thousands of years ago, then it makes sense that they would have quite an interest in us. We might be one of their grandest experiments.

What if they also experimented with other species OFF the planet Earth. If the anunnaki exist, then there are also MANY other races on other planets as well. This would only be logical. Maybe the anunnaki also used a mix between the known "ZETAS" or "GREYS" and created an Android race to serve the anunnaki.

When we analyze the descriptions of Aliens from people who claim to have been abducted, most of the aliens are described as being small grey beings that have large eyes, a bulbous head, and act almost "Android" like.

Through the great works of scholars such as Zecharia Sitchin and Lloyd Pye, we have learned that the anunnaki are said to have created Humans from the primitive man already here, and combined their genes with the primitive Neanderthal to create us.

In the Sumerian Tablets, the story of Creation and the Garden of Eden are shared. The Great Flood is also a favorite written in the tablets. These stories aren't changed all that much when represented in the Bible - however, they are manipulated. The Sumerian Tablets tell of the Anunnaki; a race of beings from Nibiru who created Humans by taking the indigenous beings on Earth and splicing their own DNA with that of the Aliens. The Anunnaki were greatly advanced beings and created the great monuments found on the Earth; Moon; Mars and other solid planets/moons within our corner of the Universe.

The purpose for creating Humans is also written in the Tablets. Humans were created to be servants of the gods. Many would have called the early humans, slaves. We were used to mine precious minerals such as gold. Still to this day, gold is considered a highly sought after mineral. Researching the Sumerian tablets will also tell you reasons for this unique status of gold.
