Many reported UFO sightings are eventually explained as:
- Aircraft
- Balloons
- Satellites
- Atmospheric phenomena
- Astronomical objects
- Drones
- Optical illusions
Some reports remain unexplained because available information is insufficient to determine exactly what was observed.
UFO vs. UAP: What’s the Difference?
In recent years, many governments and researchers have begun using the term Unidentified Anomalous Phenomena (UAP) instead of UFO.
Here’s a simple comparison:
