As a child, Mars fascinated me; perhaps billions of years ago it was as lively as Earth. Imagine Mars, cloaked in an atmosphere similar to ours, teeming with life before transforming into the frosty, desolate planet we see today. The thought of Mars hosting rivers, potentially oceans, and diverse life is captivating. It reminds us of the universe's unsolved mysteries and that even the most stable conditions can be fleeting. This story teaches us that change is inevitable, even in the most steadfast circumstances, and there are always new mysteries waiting to be uncovered.
