Beam of light on Mars pretty cool. I can't understand why people believe there is no life forms anywhere but here. We find new species of fish, squid, jelly fish, etc.., in our oceans everyday practically. New insects everyday for sure, plant life, trees, and animals are found at times as well. What is fact today will eventually be proven wrong in the future. always has always will. So why should we think that science is right about what is considered fact for life to exist on other planets? Just because almost nothing on this planet can survive on Mars, Moon or even the Sun doesn't mean there is no life form in the infinite galaxies of space that no life form could exists and live on what we consider uninhabitable terrain. A light in space could be a life form that breaks all the rules of our current belief of what is scientific fact in order for life to exists. Not just life but intelligent life.
