"The number 3600 was written in Sumerian as a large circle. The epithet for the planet also meant 'a perfect circle' or 'a completed cycle'. It also meant the number 3600." - Zecharia Sitchin, The 12th Planet
"The ancient Sumerian's got their information from the Annunaki, whose home planet Nibiru makes a passage approximately every 3,657 years, by our count." ZetaTalk
Sumerian mathematics has been interpreted to operate on a sexagesimal system, suggesting it was based on the number 60. This complex mathematical system dating back well before 3000 BC has mostly evaded understanding by those tasked with defining it.
The Babylonian civilization that supplanted Sumerian and Akkadian culture around 2000 BC also used this system to perform astronomical calculations whose influence remains with us today. That our measurements of time and circularity are defined by subsets of 60 whose base summation equals 3600 is not by happenstance.
Why the Sumerians picked 60 as the base of their numbering system is the subject of conjecture among scholars, yet the reason is obvious to those with eyes to see. As the Zetas have explained, this methodology was not developed by the Sumerians but by the Anunnaki for gauging time relative to the return of their home planet. Thus, Sumerian mathematics was not based on the number 60, but rather 3600.
THE 3600 CLUB
In addition to the compelling evidence found in Sumerian mathematics, recurring cataclysms visited upon the Earth every 3,600 years is demonstrably evident by the archeological evidence of mass extinctions and collapsed civilizations.
"The Mastodon [or mammoth] is a species that went extinct during the past few pole shifts, primarily when the grasslands they browsed in Siberia were drawn rapidly into the new polar circle." ZetaTalk
"In 1797 the body of a mammoth, with flesh, skin, and hair, was found in northeastern Siberia. The flesh had the appearance of freshly frozen beef; it was edible, and wolves and sled dogs fed on it without harm. The ground must have been frozen ever since the day of their entombment; had it not been frozen, the bodies of the mammoths would have putrefied in a single summer, but they remained unspoiled for some thousands of years. In some mammoths, when discovered, even the eyeballs were still preserved.
"This shows that the cold became suddenly extreme .. and knew no relenting afterward. In the stomachs and between the teeth of the mammoths were found plants and grasses that do not grow now in northern Siberia .. (but are) .. now found in southern Siberia. Microscopic examination of the skin showed red blood corpuscles, which was proof not only of a sudden death, but that the death was due to suffocation either by gases or water."

"A population of Woolly Mammoths greatly reduced in size are known to have lived on the island of Wrangel, which lies within the Arctic Circle off the coast of Northern Russia. Carbon isotope dating indicates that these Woolly Mammoths died out 1650 years BC, the most recent date attributed to the extinction of any Mammoth population." Source

The End of the Supe, Peru
"Nature turned against one of America's early civilizations 3,600 years ago, when researchers say earthquakes and floods, followed by blowing sand, drove away residents of an area that is now in Peru.
"Anthropologist Mike Moseley said: ‘They had no incentive to change, and then all of a sudden, boom, they just got the props knocked out from under them.’
"Moseley and colleagues were studying civilization of the Supe Valley along the Peruvian coast, which was established up to 5,800 years ago. The people thrived on land adjacent to productive bays and estuaries. The Supe fished with nets, irrigated fruit orchards and grew cotton and a variety of vegetables. They also built stone pyramids thousands of years before the better known Mayans. But the Supe disappeared about 3,600 years ago. A massive earthquake, or series of quakes, struck the region, collapsing walls and floors and launching landslides from barren mountain ranges surrounding the valley. In addition, layers of silt indicate massive flooding followed.
"Then came a change in the winds and currents in the Pacific Ocean, which brought heavy rains that damaged irrigation systems and washed debris into the streams and down to the ocean, where the sand and silt settled into a large ridge, sealing off the previously rich coastal bays. In the end, land where the Supe had lived for millenia became uninhabitable and their society collapsed." Source
Santorini and the Demise of the Minoan Civilization
"The last major explosion of Santorini occurred 3,600 years ago. The thunderous fury of nature left its mark on the island, the home of Greece's last active volcano which still smolders today. The entire center of the circular island sank into the sea during the tremendous volcanic explosion. The eruption caused tidal waves which virtually wiped out the advanced Minoan Civilization of Crete, 70 miles to the south.
"The huge mass of pumice thrown out from this eruption covered the surface of the sea over a wide region and was washed up at higher levels on the shores by the tsunamis triggered by earthquakes." Source
"In Amnissos, the port of Knossos, scientists examined findings that contained ash, marine species, cattle bones, floor and wall plaster, pumice and seashells. They figured out immediately that this could be explained only by a massive and sudden inflow of water. The only way they could have been deposited on the land of Crete was by a tsunami. The tidal wave caused by Santorini Volcano traveled and hit the shores of Crete, destroying the plantations, the crops, the ships and commerce, devitalizing and deviating the Minoan Civilization. The Minoan ports and infrastructures were destroyed by the 50 feet waves and were never rebuilt.
"Using radio carbon techniques they compared the geological findings with the eruption era and the conclusion was horrifying: not only one, but several successive tsunamis, of more than 50 feet (15m) were hitting the Cretan shores, every thirty minutes." Source
