The '''Earth''' is the third planet in the [[Solar System]]. It is the largest of the terrestrial planets<ref>"Terrestrial planets are planets made up of rocks or metals with a hard surface — making them different from other planets that lack a solid surface. Terrestrial planets also have a molten heavy metal core, few moons, and landforms such as cliffs, valleys, volcanoes and craters." [https://gml.noaa.gov/education/info_activities/pdfs/TBI_terrestrial_planets.pdf] Four such planets exist in our solar system: Mercury, Venus, Earth and Mars.</ref> and is the only known [[planet]] which has [[life]] as we know it. The surface of the planet is approximately two-thirds covered in [[water]]. The atmosphere is roughly 78% [[nitrogen]] and 21% [[oxygen]], with trace amounts of water vapor, [[carbon dioxide]], and other elements. Some Biblical scholars have calculated that the earth is around 6000 years old, using the genealogical information provided in Genesis. Some biblically illiterate scientists, however, disagree with this method of calculation.<ref>[https://www.letu.edu/academics/arts-and-sciences/files/age-of-earth.pdf  Steven Ball, Ph., "A Christian Physicist Examines the Age of the Earth”.]</ref> (See also: [[Age of the Earth]]).
