Evidence comes from Martian soil that human colonies could live on one area on the red planet. Research shows that life formerly existed for billions of years in various epochs.
Presence of Water on Mars
Clay-bearing sedimentary rocks have been located in the northwestern Ladon Valles, the southern Ladon basin, and the southwest highlands enclosing the Ladon basin, all of which are components of the heavily cratered Margaritifer Terra territory, according to pictures captured by the Mars Reconnaissance Orbiter, Science Alert reported.
One of the clues to the existence of water for long periods when it forms in neutral pH conditions of minimal water evaporation. It is believed at one point, about 3.8 billion years to 2.5 billion years had water on the surface of Mars.
Catherine Weitz, a senior scientist at the Planetary Science Institute in Arizona, gave her input about it. She added that colorful light-toned layered sediments that display relatively low bedding dips and contain clays across 200 kilometers in the distance are evidence that a lake was most likely present within the Ladon basin and northern Ladon Valles.
A lake was most probably present in the Ladon basin and northern Ladon Valles, and she continued, due to the sheer colorful, light-toned layered sediments that display relatively low bedding dips and contain clay minerals over a distance of at least kilometers, noted PSI.

It's a low-energy lake setting with clays found that sustains an environment capable of supporting life at that time in the planet's history, allowing human colonies to take a chance.
This does not prove via martin soil that life existed in any period; on earth, digging for fossils should be done on the planet to verify the hypothesis.
Searching for definitive proof that condition was perfect for organisms to live. So far, it is what is the present studies to see if conditions can be seen via the surface and sediments, citing Nation World News.
Scientists speculate that clays were created on the high ground of the Ladon basin that was later eroded by running water; that ran into a lake downstream to the basin and would flow into the north Ladon Valles.
The team determined that the southwest Ladon basin would have seen the most recent water flow. The deposits here correspond to the Eberswalde delta, a region of Mars that is located immediately south of the study area.
Study of Martian Soil
Weitz added the results show the sedimentary clay was deposited due to running water in Eberswalde is usual, this most recent time. Numerous examples of the young valleys that have clay deposits in the region.
There is compelling evidence that ice exists on Mars, with the ongoing search for water sources. A study purports that flowing water was plentiful on the Martian landscape with life as a result.
Water on Mars is the lynchpin to prove life did exist before, said researchers, how clays and other rocks seen in photos show that water is still present.
Nutrients and stabilizers are present in clays present in the environment, add water and nutrients with conditions conducive to sustain life; that will allow organisms to thrive, said the study, mentioned Science Direct.
If Martian soil does have water, as evidenced by clays should allow human colonies to use it to their advantage for extended habitation.
