It seems that Mars really had liquid water once

Due to the vast data collected by the numerous satellite and rover missions that have examined the red planet in detail, scientists are now certain that millions of years ago, liquid water flowed on the surface of Mars.

There are still a lot of unanswered questions about water in this state on Mars, such as whether the stream was something regular and normal, or something intermittent and less common, and that is important because it might help us understand if Mars was a hot planet and humid, or a cold, icy planet.

The nature of the surface and atmosphere of Mars does not allow any conclusive answer to these questions, and according to a new study by Brown University, the two hypotheses may be true. It turns out that early in his life Mars was a planet with plenty of surface ice, and that at a certain point in time, due to the increase in temperature, it had gone through a phase of melting, which produced water in liquid form in quantities enough to create the ancestral valleys we can now observe on the surface of the planet.

Researchers have tried to find a link between the geology of Mars, which suggests a hot, humid planet, and its atmospheric models, which indicate that it has been cold and icy. They have been able to demonstrate that it is likely that in the past, the planet has gone through a period of accumulation of ice in glaciers, and that during the day, temperatures during the summer caused these glaciers to melt, producing running water.

Over the years, these small deposits of water resulting from the melting of glaciers have become sufficient to create the geology that can now be observed on the planet, and will most likely have created the valleys that abound in the southern planet.
