Missing Antarctic Microbes Raise Thorny Questions About The Search For Aliens - ScienceNews

Earth is rife with life. From blue whales to prokaryotes and from the highest mountain peaks to the deepest marine abysses, yet some places seem to be potentially sterile like Antarctica's soil. Yet human science can't say with certainty that soil is sterile, which raises a conundrum for Elise Cutts about discovering life elsewhere in our solar system. Amidst the absence of evidence, the California News Times wants to know Are Aliens Real? A few scientists do weigh in, but focus on humanity's conceits and Earth's diversity rather than explictly on you-know-who to make the question a lot more interesting. On the other hand, Daisy Hernandez has 6 Solid Reasons For Believing In Aliens which are guaranteed to be reasonable enough that your greyface friends will seethe. Sadly, according to Matt Williams, We'll Have To Wait About 3,000 Years For A Reply From Intelligent Civilizations. Okay, would a stupid civilization be quicker in responding?

There are some interesting ideas bandied around here but this future doesn't seem particularly bright. (CS)
