150 million – 3,000 BCE: UFO|UAP & ENTITY Sightings Archive
Before history began recording itself, something was already here. The 150 million to 3,000 BCE archive is the deepest layer of the ThinkAboutIt Docs chronological record — a span of time so vast that conventional archaeology has no framework for most of it, yet the physical evidence, the ancient texts, the geological anomalies, and the artifacts that survive from this period tell a story that no single academic discipline has been willing to fully confront. From the Ica stones of Peru carrying images of surgery, astronomy, and human-dinosaur coexistence carved into rock 13 million years ago, to the Anunnaki colonization of the Persian Gulf region documented in Sumerian cuneiform 432,000 years before the common era, to the radioactive skeletons of Mohenjo-daro lying in the streets exactly as they fell — this archive documents the longest and most consequential non-human presence in Earth’s history. It does not begin with a sighting. It begins with creation.
The 3,000 BCE threshold that closes this archive is not an arbitrary endpoint — it marks the moment when human civilization began keeping written records systematic enough to document what it was witnessing. Everything before that threshold comes to us through physical evidence, geological anomaly, ancient oral tradition, and artifacts that the dominant academic framework has spent a century struggling to explain away. Vitrified stone forts fused by temperatures no medieval fire could produce. Uranium deposits that appear mined in antiquity. Hemispherical glass instruments with mercury inside found in Gobi Desert caves. Cave paintings in northern Spain and southern France depicting disc-like objects that predate written language by fifteen thousand years. The Dropa stone discs of the Sino-Tibetan border. The fiery Vimanas of ancient India. The saucer-shaped vessels descending from the sky recorded in China’s oldest historical texts. The archive holds all of it — from the beginning.

Location: PERU
Summary: The Ica stones of Peru — thousands of engraved andesite stones found near Ica, Peru — depict detailed images of surgery, transfusions, star maps, telescopes, and human beings coexisting with dinosaurs. The stones have been dated to approximately 13 million years ago by some researchers. Their precision of detail and consistency of subject matter across thousands of individual stones argues against modern forgery.

Location: Persian gulf area
Summary: According to Zecharia Sitchin’s translations of Sumerian cuneiform tablets, the Anunnaki — described as beings from the planet Nibiru — arrived in the Persian Gulf area approximately 432,000 years before the common era, establishing colonies and initiating genetic engineering that ultimately produced Homo sapiens through the merging of Anunnaki DNA with that of existing hominids.

Summary: according to Scientology Xenu was a galactic ruler, who ordered the Nuking of the Earth.
Fused Green Glass indicative of a nuclear explosion has been found in the Egyptian Desert; Euphrates Valley; Gobi Desert; Iraq; Libyan Desert; lop Nor Desert, China; Mojave Desert; Pierrelatte, Gabon; Scotland and Turkey.Highly Radioactive Skeletons were found in Rishi, Mohenjo Daro, Pakistan. Radioactive Dust still in geologic strata in the areas of the American southwestern Deserts, African Deserts, and Gobi Desert. Geologists can’t explain the “fused green glass” that has been found in such sites as Pierre-latte in Gabon, the Euphrates Valley, the Sahara Desert, the Gobi Desert, Iraq, the Mojave Desert, Scotland, the Old and Middle Kingdoms of Egypt, and south-central Turkey. 
These skeletons are among the most radioactive ever found, on a par with those found at Hiroshima and Nagasaki. Ancient cities whose brick and stone walls have literally been vitrified, that is– fused together like glass, can be found in India, Ireland, Scotland, France, Turkey and other places. There is no logical explanation for the vitrification of stone forts and cities, except from an atomic blast.
From the same time period, scientists have found a number of uranium Deposits that appear to have been mined or Depleted in antiquity. When the Rishi City of Mohenjodaro in Pakistan was excavated by archaeologists in the last century, they found skeletons just lying in the streets, some of them holding hands, as if some great Doom had suddenly overtaken them. The Lop Nor Desert in western China is known to be the center of a great UFO mystery. Scientists Drilling Down in an excavation near Babylon, in Iraq, found various strata containing evidence of Different civilisations. They eventually stopped when they hit a solid wall of glass, like the sand had been fused together by a nuclear blast. (Date estimate not given.)

Location: Baian Kara Ula, Sino-Tibetan Border, Hunan Province, China. The Dropa Stone Discs
Time: Not recorded
Summary: The Dropa stone discs — 716 grooved stone discs discovered in caves in the Baian Kara Ula mountains — were found alongside the skeletal remains of small beings with large heads. The discs contain a spiral groove that under electron microscope examination reportedly revealed microscopic hieroglyphic writing. Translations claimed to describe a spacecraft crashing in the mountains 12,000 years prior to the discs’ creation — suggesting a presence dating to approximately 47,000 BCE. [Full report]

Location: INDIA — Rama Empire (modern India and Pakistan)
Summary: Indian country of Rama existed. Remains of their large cities still exist in the Deserts of India and Pakistan (Mohenjo daro). Indian texts from this period tell of anti-gravity space ships (called Vimanas, or Astras), and a war with the Atlans on the moon. Curiously, Soviet scientists have Discovered what they call “age-old instruments used in navigating cosmic vehicles” in caves in Turkestan and the Gobi Desert. The “devices” are hemispherical objects of glass or porcelain, ending in a cone with a Drop of mercury inside. Some ancient Indian texts Describe a war with Atlantis (who flew Vailixi machines) using flying machines and atomic bombs about 10,000 to 12,000 years ago.

EXECUTIVE SUMMARY:
Before the Record Began — The 150 Million to 3,000 BCE Archive
The 150 million to 3,000 BCE archive is unlike any other page in the ThinkAboutIt Docs chronological record because it does not document sightings in the conventional sense — it documents presence. A presence so ancient, so continuous, and so deeply embedded in the physical record of this planet that the conventional academic framework has spent over a century developing increasingly elaborate explanations for why it cannot mean what it appears to mean. Vitrified stone cities. Radioactive skeletons. Fused green glass in fourteen locations worldwide. Hemispherical mercury navigation instruments in Gobi Desert caves. Disc-like objects in Paleolithic cave paintings. A fully formed civilization in Sumer appearing without precedent. Cuneiform tablets describing beings from the sky who created humanity. The Ica stones carrying surgical and astronomical knowledge millions of years before any human hand was supposed to be capable of carving it. The archive holds all of it without apology or editorial filter — because the record is the record, and the pattern it describes is the oldest and most consequential in the entire ThinkAboutIt Docs archive.
What the 150 million to 3,000 BCE archive ultimately documents is not a beginning — it documents a continuity. The same non-human intelligences whose craft appear in cave paintings 17,000 years ago appear in Sumerian cuneiform 6,000 years ago, in ancient Indian texts 13,000 years ago, in Chinese records 3,000 years ago, and in the modern government release of declassified UAP files in May 2026. The archive does not argue for a single theory of who they are or what they want. It records what was documented, what was built, what was written, what was carved, what was found in the earth, and what has never been adequately explained. The earliest entry in this archive predates human existence by 150 million years. That is not a gap in the record. That is the record.
“Sons from the sky descended to Earth on a star which was the shape of a saucer.”
