Earth is the only planet with both water and land which allows life to exist. It tilts on its axis creating seasons and day/night as it rotates, and its gravitational pull holds the atmosphere close. The tilt of the Earth's axis is important for regulating temperatures, as if it tilted closer to the sun it could melt the North Pole while making the other side very cold.
