A "city wall" is suspected to appear on Mars. Who built it?

Humanity’s exploration of Mars has never stopped. Scientists agree that the conditions on Mars are very similar to those on the Earth. Through a large number of observations and data analysis, they have concluded that there is a source of water on Mars. It's just that the surface temperature of Mars is relatively low, and all of it is underground glaciers, which provides conditions for the gestation of life.

People infer that life existed on Mars, even advanced civilizations. With the continuous advancement of modern science and technology, humans have launched Mars exploration satellites and Mars exploration rovers, and some photos have been sent back from Mars. Very strange, found many pyramid-shaped buildings and strange light sources!

Not long ago, the U.S. Mars Exploration Rover InSight was exploring the plains near the equator of Mars and photographed white bricks under a soil layer. Judging from the photos, these rectangular bricks The stones are like the remains of ancient buildings, with cross-sections on them. They look very old. Scientists believe that this is a city wall site. If conditions are sufficient, digging here will definitely turn out to be a wall, but human technology is not yet high enough. It has landed on Mars, and the photos taken are not very clear, and there is a lack of necessary detection data, so it is difficult to say whether this is an alien relic of Mars.

As soon as this information was released, it aroused the interest of the majority of astronomy enthusiasts. Most people believed that there had been civilization on Mars, but because the living conditions on Mars became harsh, the Martian civilization died. Although there is no substantial evidence yet to show the emergence of life or civilization on Mars, this does not prevent people from fantasizing about Mars.

You must know that Mars is located in the habitable zone of the solar system, with a moderate distance and distance from the Earth. The same gravity and huge amounts of glaciers provide the necessary living conditions for humans. Mars has always been the first choice planet for human interstellar immigrants.

Due to the continuous development of modern science and technology, the rapid expansion of the global population and the intensification of pollution, the earth will soon reach its limit, so humans will actively want to immigrate to the interstellar space. According to the famous American entrepreneur Musk The Mars Immigration Plan, SPACE-X plans to create the Mars era in the next 20 years, and establish a human Mars base by sending dozens of Mars launch vehicles. After the infrastructure is prepared, astronauts will be sent to Mars through manned spacecraft, and Mars The two core goals of the plan are to establish a human base and explore life on Mars.
