Most people are aware of the many unique characteristics of the Earth that make life on it possible.
These characteristics include such things as the composition of the planet and the atmosphere, the tilt of the axis, the presence of the Moon, the shape of Earth's orbit, and the distance from the Sun. The Earth's distance from the Sun is obviously critical in that if Earth were significantly closer or farther from the Sun, Earth would be respectively much warmer or colder than it is now. Consider Venus, the next closest planet to the Sun. Being hot enough to melt lead, it is obvious that life cannot exist on Venus. It is generally believed by evolutionists that Venus's closer position to the Sun caused its early temperatures to be higher than Earth's, so that any water that it may have possessed boiled away long ago.
