New findings hint that rather than Mars' atmosphere having been worn away by billions of years' worth of solar winds, it might just be contained somewhere beneath the martian surface. Evidence from gullies and channels shows that Mars' water layer may have been more than half a mile deep in places. To have this much water in liquid form, Mars must have had a much higher atmospheric temperature, which could have been made possible by a strong greenhouse effect in Mars' past. Another theory is that the atmosphere could have been blown away by the impact of a gigantic space rock striking the planet. Now discovering what happened to Mars' atmosphere is the key to the door which shows the answer to whether or not life did ever exist on Mars. This would make the idea of life existing in Mars much more solid.
I think that discovering the answer to this problem could lay a foundation for the idea that life did exist on Mars. From this foundation scientists could easily do more research. For as long as I can remember, scientists have been trying to figure out whether or not life existed on Mars. Now, if they can discover more about Mars' atmosphere, this problem could finally be solved.
