Scientific advances over the last two decades allow astronomers to detect planets orbiting stars outside our solar system. These objects are known as extrasolar planets, or exoplanets for short. As astronomers study the hundreds of exoplanets already discovered, evidence for Earth's rare (or possibly unique) characteristics for supporting advanced life continues to grow. News reports often claim a particular exoplanet is Earth-like or "habitable." Such announcements typically reflect a "minimalist model" for habitability, namely the assumption that where liquid water exists, life will inevitably exist. RTB's testable creation model proposes that life requires far more exacting criteria than just liquid water.
