A Billion Years Ago... — The Wildest UAP Theory Explained by Former Navy Admiral

The speaker discusses theories about the origin of unidentified aerial phenomena (UAP), suggesting three main possibilities: an extraterrestrial source, an interdimensional origin, or an ancient advanced civilization on Earth that may have relocated underground or to another celestial body like Mars due to past cataclysms. As an example, they reference a documented USO (unidentified submerged object) case from the 1960s, where Canadian divers reported seeing underwater discs and non-human occupants. The speaker emphasizes the need for serious scientific study and laments the stigma surrounding the topic, while also noting ongoing research efforts, such as the Galileo project, which aims to collect and analyze potential non-earthly materials.
