Earth 

Earth has been called the third rock from the Sun.

As far as we the common folk know, Earth is the only planet on which life exists.  If life is discovered on any other planet, or anywhere in the universe, some religious beliefs may need to be altered to meet with reality.  Religions really do not like having their 'facts' disproved by anyone.

Earth is located about 93,000,000 miles from the Sun.

Earth has been called the Blue Planet.

Earth has one probably natural moon that is called the Moon.  It also has a lot of man-made objects rotating around it.

At one time it is said that people considered the Earth to be flat as well as being the center of the universe.  In the past people, including Masons, were often imprisoned, tortured or killed by the Catholic Church, and others, for believing otherwise. 

The term Earth is sometimes used to indicate dirt or soil. Earth was at one time considered to be one of the original four elements.

The Earth is close to being a Sphere, but is really an Oblate Spheroid.
