Mega Tsunamis means Mars once had oceans. If Mars had oceans, it may mean the red planet had life. Some suggest that Mars’ life may be underground. What if life there came to earth? What if we are the Martians? What if we lived on Mars and were a technologically advanced civilization with the ability to build spacecraft? What if we had to escape a disaster (The scientist claim meteors cause the tsunamis) and traveled to Earth?
It’s always fun to speculate about such issues, even if it’s only exercise for our brains.
