Are there already astronauts on the Red Planet operating in secrecy for NASA and other space agencies?
Or maybe we have already designed a form of artificially intelligent robot that’s helping maintain the rovers. Mars is clearly the perfect testing ground for such a machinery.
Other UFO enthusiasts have once again proposed the idea of Curiosity rover being somewhere on Devon Island, Canada, instead of Mars. This is a reasonable point of view that would explain the presence of human beings (or just beings) in spacesuits.
However, these remain only speculations based on our disbelief in governmental institutions, but there’s a good chance for this to be more than just a conspiracy theory.
