Atmosphere Fine-Tuning

TNRTB Archive - Retained for reference information

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.

Reasons to Believe emerged from my passion to research, develop, and proclaim the most powerful new reasons to believe in Christ as Creator, Lord, and Savior and to use those new reasons to reach people for Christ. Read more about Dr. Hugh Ross.
