Buga Sphere Metallurgical Analysis and Preliminary Summary:

October 17, 2025
1. The Buga Sphere has been carbon-14 dated by the University of Georgia at 12,560 years
old. This is 8000 years older than the Great Pyramid of Giza.

2. Metallurgical analysis at a separate certified lab found that the sphere is an aluminum
alloy including several rare earth elements with electrical and magnetic uses. Some of
these elements were not known to human science until the late 1800s and 1900s. THE
ALUMINIUM ALLOY COMPOSITION DOES NOT MATCH ANY KNOWN EXISTING ALLOY.

3. Aluminum was not industrialized until aŌer 1876, when the technology for refining it
was invented. Before then, aluminum was rarer and more valuable than gold.

4. The shell of the Buga Sphere has components woven into it – including fiber opƟc
material – unlike modern manufacturing technology. It is more akin to a sophisticated 3D
printer. Note that fiber opƟcs were the result of the study of crashed extraterrestrial
craft recovered in the 1940s and aŌer.

5. Two independent linguistic experts have concluded that the symbols on the Buga
Sphere are a type of proto-Sanskrit. Translations indicate a warning about some cosmic
radiation or astronomical event that could affect Earth’s geophysical stability. NOTE: the
Buga Sphere dates from 12,560 years ago, around the end of the last Ice Age, which
some believe ended due to some global catastrophic event.

6. We now have 5 independent videos of 5 separate, apparently identical, Buga Spheres
operaƟng in the general region of Buga, Colombia, South America. Only one has been
retrieved physically.

7. While it is unknown why these objects have been acƟvated aŌer 12,560 years, I
hypothesize that some magnetic field anomalies have been detected, and they are an
early warning technology of a future geophysical event that could be catastrophic. Note
that scientists have been mapping a large area of magnetic field changes over part of
South America.

Preliminary Conclusions: The Buga Spheres are of likely extraterrestrial and/or
nonhuman origins, or from an unknown Earth civilization with advanced technology,
including anƟgravity propulsion and energy generaƟon (non-nuclear). If from an Earth-
based civilization, that civilization likely had contact with and technology from
extraterrestrial civilizations. The acƟvaƟon of these Buga Spheres may be an early
warning technology of a possible significant and civilization-changing event in the
relatively near future.

NaƟonal Security and global security authorities should be made aware of this pending
future development.

We conƟnue to do further research on the Buga Sphere.
