UFO vs. UAP: Clarifying Terminology, Reporting, and Scientific Inquiry
To the point
UFO is the old, culturally loaded idea of a visible object in the sky, while UAP is a broader, neutral term for unidentified phenomena that may occur in air, water, or other mediums and do not assume a physical flying vehicle, with governments using UAP for standardized reporting and scientists generally attributing most cases to ordinary explanations but leaving a few unresolved.
