Was Mars once as lush and green as the Earth and teeming with life? This is an examination of the new photographic evidence that has been collected by multiple probes (over the last 20 years or so) that provide a fresh look at potentially artificial structures on Mars. The new photographic detail makes an even more compelling case for artificiality.
It seems clear that highly-evolved beings did once inhabit a technologically advanced civilization on Mars. Photos taken by twin rovers Spirit and Opportunity, followed later by Curiosity, of many unmistakably mechanical-parts artifacts and clearly skeletal remnants, strewn across the Martian surface, otherwise indicative of some ancient cataclysm that undoubtedly destroyed the civilization there.
