Mars Had Oxygen-Rich Atmosphere 4 Billion Years Ago, Shows New Study

Scientists from Department of Earth Sciences at the University of Oxford analyzed the compositions of Martian meteorites found on Earth and data from NASA’s rovers. The fact that the surface rocks are five times richer in nickel than the meteorites was puzzling and had cast doubt on whether the meteorites are typical volcanic products.

I so knew it. Mars was just like Earth billions and billions of years ago, then some catastrophic event turned, natural or otherwise, turned it into the red crust of a planet we know it as now. Fleeing people/aliens of this planet so close to us would account for some "ancient alien" theories. Also, if natural, probably shows what will happen to Earth when it reaches that point.

Agreed Cody; we do need physical fossil evidence before we can enjoy any definitive Eureka moment.
None forthcoming - yet.

Having said that, we are spending a lot of time and money on checking it out.
Obviously a happier hunting ground than the Moon ...
