Today the surface of mars is colder than the Siberian Winter and dryer than Gobi Desert. Yet we both know that things on earth live in both places as a matter of fact an article from Scientific American reported that there are microbes that live in radiation infested rock at 200 plus degrees 2000 feet underground. We have found microbes that eat radiation and live in sulfuric gas and lava flows. See the scientific paper in Discover magazine 1999, “To Hell and Backâ€Â. So how can anyone deny that there is life on mars and there was also life 3.6 Billion years ago? And heck that is just the nearest planet. There is life all over this galaxy and all the others too.
