The Sumerian tablets have an explanation which actually fits both the physical configuration as well as other abnormal elements of our solar system.
Among other things, a planet like earth with one moon the size of our existing moon is unusual.
The tablet explanation is that there is another planet in the solar system with an orbital period of several thousand years which is several times the size of the earth which has had interaction with the outer planets over the course of history; one of its moons impacted the Earth in the present area of the Asteroid Belt resulting in the thin Earth crust in the Pacific and reducing the size of the planet significantly; and further resulting in the capture of the current Moon as proximate to the Earth.
Elijah Sithen’s “translation” of the tablets has the period of the tenth planet at 3500 +/- years however MIT scientists have developed a thesis that the actual period is between 4350 and 4400 years.
There is also a text out on Amazon which supports belief in God the ultimate creator as being the God responsible for the present condition, perhaps in part through the vehicle of interaction with a tenth planet.
Elijah Sithen? You mean Zecariah Sitchin? His entire corpus of work is rubbish.
