Comprehensive Historical UFO/UAP Research Database

1. EARLIEST HISTORICAL MENTIONS

Ancient Written Records (2nd-1st Millennium BC)

Mesopotamian Sources:

Babylonian Cuneiform Tablets: The earliest documented references appear in Babylonian cuneiform tablets from the Šumma ālu series and other divination texts from the second and first millennia B.C. These describe “changing shapes in the sky” and “black meteors,” interpreted as religious omens and harbingers.

Egyptian Claims:

The Tulli Papyrus (1440 BC): Claims to document a mass UFO sighting during Pharaoh Thutmose III’s reign, describing “circles of fire” in the sky. However, this document is considered a modern hoax by scholars, with Jacques Vallee and Chris Aubeck describing it as “somewhat too convenient a find” and likely copied from Alan Gardiner’s Egyptian Grammar (1927).

Cave Paintings and Ancient Art

Indian Subcontinent:

Charama Cave Paintings (10,000 years old): Discovered in Chhattisgarh, India, featuring humanoid figures lacking facial features and appearing to wear protective suits
Hoshangabad District Paintings (10,000 years old): Rock paintings in Madhya Pradesh depicting what some interpret as UFOs and extraterrestrials

Global Distribution:

Tanzania (29,000 years old): Ancient cave paintings featuring similar motifs
American Southwest (7,500 years ago): Sego Canyon petroglyphs in Utah showing large-eyed, antenna-bearing humanoid figures with rectangular heads

Biblical References

Ezekiel’s Vision: The prophet Ezekiel’s description of wheeled chariots with cherubim, interpreted by some as spacecraft encounters, though biblical scholars view this as throne iconography using Babylonian royal symbolism.

Elijah’s Ascension: The “fiery chariot with fiery horses” that carried Elijah to heaven (2 Kings 2:11), interpreted by ancient astronaut theorists as technological transport.
