Astronomers traditionally consider the nearest large planets - Venus and Mars - among potential candidates for the existence of life in the solar system. The sizes of these planets and the distance from these planets to the Sun make them quite suitable for the existence of organic life typical of the Earth.
With the beginning of the space era and flights to these planets of various kinds of probes, Venus was at first excluded from candidates for organic life, since the temperature there is 800-900 degrees Celsius, which, to put it mildly, is not comfortable for the existence of protein life. However, new studies, more precisely, mathematical calculations and computer simulations, indicate that 800 degrees on the surface of Venus were far from always.
Venus's current climate is the result of numerous volcanic eruptions that have transformed the atmosphere into solid carbon dioxide with clouds of sulfuric acid. But up to this point, the temperature there was quite acceptable. Moreover: according to the myths of the Indians of Central America, the main god of their pantheon, Quetzalcoatl, who taught the Indians of civilization, flew from Venus, where he later departed. However, it is still impossible to confirm or deny this, since the clouds on Venus are so dense that the surface is not visible even from orbit.
With Mars, everything is much simpler, for some reason it almost lost the atmosphere, as a result of which astronomers perfectly see all kinds of anomalies on the surface of Mars.
We do not take photos and videos from the “rover” into account, since most likely this “rover” rolls somewhere in the Mojave Desert in Nevada and from time to time “sends to Earth” photos of old shoes and fragments of household garbage lost by local Indians. However, the NASA space television series does not cancel the Sphinx, the complex of the Martian pyramids and the Monolith:

The position of the officials on these photographs is well known: the play of light and reflection, optical illusion and so on. However, tireless seekers of truth from the Above Top Secret forum fished this photo from the official NASA servers:

As you can see from the photograph, the right angles of the object buried under the sand are beyond doubt. The likelihood that they appeared spontaneously is ridiculously small. Unless we can assume: a square meteorite fell on Mars, forming the same square crater.
Whether this object is the remains of the fortress walls or something else, we do not know, but it is clear from the photograph that there was at least intelligent life on Mars. The only question that remains unclear is why the existence of civilization on Mars, at least in the past, is so stubbornly denied by the officials? What are they hiding from people?
