| Status | DEBUNKED |
| Summary | In the late 19th century, astronomers like Giovanni Schiaparelli and Percival Lowell observed linear features on Mars through telescopes, interpreting them as artificial canals built by intelligent Martians. This theory captured public imagination but was later debunked as an optical illusion when better telescopes and spacecraft revealed no such structures. |
| Origin | 1877, when Schiaparelli first described 'canali' on Mars; popularized by Percival Lowell in the early 20th century. |
| Claimed |
|
| Evidence / consensus | The features were optical illusions or natural formations; spacecraft imagery shows no canals. |
