No, it is not true that Martians are aliens. The term "Martian" refers to beings or things that come from or are associated with the planet Mars. While the possibility of life existing on Mars is still being explored, there is no confirmed evidence of aliens or extraterrestrial life on Mars or any other planet.

Martians are fictional alien beings from Mars. Aliens are fictional beings from another planet, which may be Mars or anywhere else but Earth. In other words, "aliens" is the main category, "Martians" are a subset, meaning just the aliens that happen to be from Mars.
