Did We 'Kill' Martian Microbes? New Analysis Of Viking Mission Points To Life On Mars

Extraterrestrial life is something that I find quite intriguing. It's very hard for me to believe that of all the thousands of galaxies and hundreds of thousands of celestial bodies out there, Earth is the only one with life. That's not to say that I believe there are other intelligent two-legged creatures out there, but life began on this planet and it's quite likely it began on other planets.
