A sumerian myth about Nibru is 'Enlil and the E-Kur'. Here is a small sample of the myth's translation: "Enlil, when you marked out the holy settlements, you also built Nibru, your own city." The city of the sumerian god Enlil(Ellil) here is called Nibru. This city is known today as Nippur and this name has striking similarity to the name Nibru. Also the Temple of Enlil is, or was, in Nippur.
According to the sumerian Flood myth, Enlil wanted to flood the people because he could not sleep. So he planned this flood and told the other gods not to tell anybody about this. Enki(the wise-one, the al-knowing one) dit not want his creation (men) to die for this. Before the flood, the myth says that the Gods depart from the earth.
Beside the myth, we can understand that the gods are creatures, just like us. And also Enlil should leave earth, because his city Nibru would be flooded. Not a Planet.
Another sign to the city Nibru, is the bond, Duranki. Dur-an-ki is sumerian for; “The Bond between Heaven and Earth”. Dur: a Bond between somethings, An: Heaven and Ki: Earth, Making Duranki. What has this to do with Nibiru? Well, Nibiru is also know as “the Ferry” or the “Planet of the crossing” or the sumerian “Winged planet” there is also a symbol from ancient sumeria of the winged planet.
The “winged planet” refers to be a comet or some sort.
And “the Ferry” is an extra name given by some theorists.
The Planet of the Crossing however, is the original meaning, but also this is been wrongly interpreted. The planet is earth, and the crossing is Duranki in Nibru(Nippur). So you could say that it is not Planet of the Crossing but the City of the Crossing.
This does not mean that Planet X, that is given the name Nibiru, does not exist. According to the Mayans, a calandar will end in the year 2012, and a new one begins, and this calandar hail's the coming of the Red Comet. This red comet is, possibly, also know as Wormwood.
Wormwood: This is discribed in the book of Revelations in the bible. The bible says that archangels throw down thunder and lightning. If you read the book Revelations carefully, you read that the writer of Revelations is exually describing comets raining on the earth, turning the rivers and seas into blood, this is because of the fosfor and iron inside the comets coloring it red, like blood. Also fire is discibed because of the comets treveling through the ozon-layer. All of this could have come from the Red Comet, if the Red Comet is Wormwood.
In the book of Revelations, there is a very strange sentence: “8:12 The fourth angel sounded, and one third of the sun was struck, and one third of the moon, and one third of the stars; so that one third of them would be darkened, and the day wouldn't shine for one third of it, and the night in the same way. “. This is not just an angel doing something, this could be one of two things, the cloud of the Red Comet is darkening the sky, or this is the gravitational pull of the Red Comet. Halting the earth's cycle for a while and slowing it down for a third.
These day's, scientists have found and track a planet they named Sedna. This planet is reddish of color and is believed to be planet X, but this could not be, because of the distance and the size of the planet. Sedna is a little smaller compared to our moon. But the size is not sure yet, because Sedna is still so far away. And this planet, or comet, should be very visable in the sky according to the legends and mythology.
And an other observation of scientists have discovered to coming of a very large object. This object is a brown-dwarf(an unborn star). Sinds a lot of stars in the Universe are binary stars (meaning that it is usually two stars circling around each other), than there is an possibility that also our star (Sol) is binary. The coming of the brown-dwarf is near and our star is going into a frenzy (causing extra heat to the green-house effect) This brown dwarf is not very visable until it reaches near our sun. The brown dwarf has a dust cloud around the surface. This will look like a planet with wings of fire (The Winged Planet). At the moment, a very big telescope is being constructed on the south-pole to watch the sky for the brown dwarf. It is believed the brown dwarf will come from the south passing us. Legend from the Mayans says, that the Red Comet will hit Earth at the seventh time it passes by, And this is the sixth time if the Red Comet passes us.
