...life exists? After more than 40 years of space exploration, I can't believe that NASA hasn't even found a microbe anywhere else in the solar system, let alone the universe. Life exists in geothermal vents. How could it not exist on Mars, at least microbial life? I believe there's a conspiracy in NASA to keep everything a secret from the public. The NASA crowd even has it drilled into them to use the same standard line when asked about the existence of alien lifeforms: "It would be arrogant of us earthlings to think that we are the only life in the entire expanse of the universe". The NASAites all say that in unison. They seem so obsessed with covering up everything that they still won't even definitively say if they've found water on another planet. Are we just going around in circles with NASA because I'm absolutely convinced they'll never admit to ETs, not even an amoeba on Europa?
