Improbable Planet: How Earth Became Humanity's Home is unavailable, but you can change that!

The Latest Scientific Discoveries Point to an Intentional Creator Most of us remember the basics from science classes about how Earth came to be the only known planet that sustains complex life. But what most people don't know is that the more thoroughly researchers investigate the history of our planet, the more astonishing the story of our existence becomes.

surface layer consumed this oxygen nearly as fast as it was produced. This oxidation process might have been completed more rapidly, but lower solar luminosity (see fig. 6.2) and much higher atmospheric methane levels—at least 100 parts per million by volume[6]—slowed it down. A large quantity of methane in the atmosphere requires a huge abundance of methanogens (methane-producing bacteria) on Earth’s surface. These methanogens work in tandem with photosynthetic life to transform carbon dioxide
