Resilient Life on Earth Increases Possibility of Extraterrestrial Life

Believe it or not, there are organisms on Earth that can survive unimaginable conditions! These beings are called extremophiles, and they’re nothing short of amazing. One example is the tardigrade, which can live in the most extreme heat, cold, dehydration and radiation. The simple fact that these organisms exist give us reason to believe that life elsewhere in the universe exists as well. There are plenty of other rocky exoplanets like earth that experience very extreme temperatures, radiation and x-rays. If these little organisms can survive it on our planet, there shouldn’t be a reason why similar organisms couldn’t survive these conditions elsewhere!
