Aliens are perhaps the most debated cryptid category, spanning UFOlogy and science fiction. They are often described as technologically superior beings from other planets or dimensions. Notable sightings include Roswell (1947) and the Phoenix Lights (1997), sparking global interest. Popular alien types include the Greys, Nordics, and Reptilians. Their purposes range from scientific observation to abduction, genetic experiments, or even interstellar diplomacy. Aliens dominate conspiracy theories and have left alleged physical traces like implants or radiation marks. Governments like the U.S. have slowly disclosed military footage confirming unidentified aerial phenomena (UAPs). While the scientific community remains skeptical, global belief persists.
