Was Mars also like Earth? Scientists believe that a few billion years ago, Mars was a human habitable planet just like our Earth, where it has clouds, winds, a roughly 24-hour day, seasonal weather patterns, polar ice caps, volcanoes, canyons, and other familiar features. A Billion Years Ago: To comprehend the possibility of Mars being Earth-like, we must delve into its ancient history. Approximately four billion years ago, both Earth and Mars were young, rocky planets with active geological processes. Both planets boasted liquid water on their surfaces and potentially harbored the conditions suitable for life to emerge. Mars, like Earth, likely had a thicker atmosphere, shielding its surface from harmful solar radiation and providing the necessary pressure for water to exist in its liquid state. Evidence from geological features, such as ancient river valleys, lake beds, and minerals formed in the presence of water, suggests that Mars was once a wet and hospitable environ...
