They left fragments of their lives on Mars. Researching this, I learned from reading the work of other scientists that Mars experienced a loss of atmosphere in the distant past. Imagine a planet with life suddenly venting its own atmosphere on a planetary scale. Nowhere to run. Nowhere to hide. The end must have been an apocalyptic experience.
I have spent decades looking at imaging of Mars and I am going to share with you the fruits of my labor in this regard. I gathered imaging taken of Mars over the years from ESA and NASA, and using large area scans looked for reflectivity on the surface. I also looked for signs of life that would be left behind after a cataclysmic event. Scientifically speaking, that is the fate of most advanced civilizations over time. We do not know yet what caused Mars to lose its atmosphere, but in time we will find out.
For thousands of years, human civilization on Earth has been told that it is the only intelligent life in not just our solar system, but the universe. It is in that story of human development and socialization that has provided the glue to keep all human tribes on Earth aligned in one single fundamental belief, where little common ground can be found in all others.
The truth is, however, that human life on Earth was not the beginning. There was advanced humanoid life on Mars as well from long ago. No one knows for sure how long ago.
We can only see in absolute amazement what they left behind. What I am finding should be enough scientific evidence to demand funding to travel to Mars and dramatically increase funding for such space missions as soon as possible, and as technology allows.
What I am finding is simply priceless and irreplaceable.
The Monument
They are carvings upon what can be described as a monument, wearing armor not unlike the early Roman Empire period. The armor is constructed like the Lorica Manica and Lorica Segmentata. At the top of the monument is a carved figure with symbols. The monument is illuminated from the sun upon the surface of Mars.
