This amazing Mars Curiosity image shows two road signs one with written text on it. A dog, a hinged open case that looks like an open briefcase but could be a solar charger or computer,several stone paved walkways,a body of water and a set of stairs.
These can be seen with startling clarity. The writing on the sign is both evenly spaced and evenly sized and looks very
similar to road signs on earth.
One of several things must be happening. Either NASA never sent a rover to Mars and these images are being taken here on earth. Or
There are people currently living on Mars with a civilization similar to ours. Or. We have colonized Mars
and the public has not been told about it.
