Earth (Latin: Terra, Tellus; gr.: Γαῖα, trb .: Gaja) - the third, counting from the Sun, and the fifth largest planet in the Solar System. In terms of diameter, mass and density, it is the largest rocky planet in the Solar System. The land is inhabited by millions of species, including humans. It is the only known place in the universe in which life occurs . According to data collected using the isotopic dating method, the planet was formed around 4.54 ± 0.05 billion years ago.

In the first billion years after the formation of the Earth inside its oceans, life appeared. The living organisms living on Earth consist of a biosphere that affects its atmosphere, hydrosphere, lithosphere and other abiotic factors of the planet, allowing the development and growth of the number of aerobic and anaerobic organisms and the formation of ozoneospheres. The development of life on land and in water has enabled the ozone layer and the Earth's magnetic field, reducing the intensity of ultraviolet radiation , and the magnetosphere, reflecting particles of solar wind and cosmic radiation. The distance separating the Sun from Earth, its physical properties and its geological history are the most important factors that allowed organisms to live and evolve. The biological diversity of the Earth is constantly growing, although in the history of Earth's life this process was interrupted several times, when mass extinctions of species took place. Although scientists estimate that about 99% of species of living organisms (about 5 billion) ever living in the Earth are considered extinct , there are still around 10-14 million species . , of which 1.2 million have been documented .
