HARD FACTS: Why Is The Earth’s Gravity Exactly Right To Maintain Our Livable Atmosphere?

Is this by chance or by design?

“The surface gravity of Earth is critical to its ability to retain an atmosphere friendly to life. If Earth’s gravity were stronger, our atmosphere would contain too much methane and ammonia. If our planet’s gravity were weaker, Earth wouldn’t be able to retain water.

“As it is, Earth’s atmosphere has a finely calibrated ratio of oxygen to nitrogen — just enough carbon dioxide and adequate water vapor levels to promote advanced life, allow photosynthesis (without an excessive greenhouse effect) and provide sufficient rainfall.” — God’s Crime Scene, J. Warner Wallace.
