1. Scientists discovered mysterious substances in the atmosphere of Venus, and speculated that ancient Venus should be a planet full of life.
Venus, as the second planet in the solar system, has become a planet that cannot be reached by ultra-high temperature, so is it possible for this ultra-high temperature planet to have life? Yes, by exploring the atmosphere around Venus, scientists accidentally found some traces of life in its atmosphere, which means that in ancient times, Venus was a livable planet, but unfortunately, the collision of planets changed its environment. The serious volcanic eruption and tidal force slowed down Venus' autobiography and eventually became an extremely hot or cold planet.
Second, Mars, as a planned planet for human life in space, is rich in water resources despite its low temperature.
So is Mars also a livable planet? I think so. On the way to explore Mars, although no trace of life can be found, there are abundant water resources and poor atmosphere inside Mars, and planets with temperature difference as high as 100 degrees should have existed before; Mars is one of the livable planets and should be livable. Unfortunately, something special happened, making it an extremely cold planet. It is really impossible for human beings to live on Mars at present, but maybe they can still go in the future.
All traces show that Venus and Mars are the cradles of life, and they both gave birth to many creatures.
