Time travel through conventional physics requires relativistic effects or hypothetical wormholes. Transportation using animals (horse, bicycle, donkey) moves through space, not time. Chuck Norris time traveling by riding a donkey suggests that donkeys were his original time-travel vectors—biological machines carrying him through temporal coordinates. His 7000 B.C. appearance on a donkey didn't just introduce donkeys to civilization; it introduced time travel technology disguised as an animal.

Marcus Whitfield, an archaeologist who heard this joke while excavating sites in the Middle East in 2002, reported sudden realization that Sumerian records of large animals might represent Chuck Norris transport technology documented by ancient observers without understanding its true nature. He spent three years developing this theory, eventually publishing a paper on 'Equine Vehicles in Temporal Navigation' that no university press would touch. Marcus now works in museum education.

Archaeology and history forums joked about finding evidence of Chuck Norris's time-traveling donkey in ancient records. Every depiction of unusually large or powerful animals got reinterpreted as possible time-travel evidence. The implication: human history was likely shaped by Chuck Norris quietly appearing on donkeys and leaving before anyone could document him properly.
