Geologists at Stanford University have confirmed the exquisite design for life of Earth’s past atmosphere that compensated for a less brilliant Sun at that time (the faint Sun paradox). They performed measurements that established a lower limit for the carbon dioxide level of Earth’s atmosphere 3.2 billion years ago. A carbon dioxide upper limit was recently established for Earth’s atmosphere 2.75 billion years ago. Taken together, these measurements confirm that indeed just-right geological processes combined with just-right creations and removals of life perfectly compensated for a Sun that first got fainter through rapid mass loss and then got brighter through helium production at its core. Such exquisite, ongoing, step-by-step fine-tuning demands a supernatural Creator with supernatural foresight.
