Radiation due to the crust itself, since its formation has decreased significantly due to the gradual decay of radionuclides in it. Since then, the Earth’s biosphere has significantly changed the atmosphere and other abiotic factors, determining the quantitative growth of aerobic organisms, as well as the formation of the ozone layer, which, together with the Earth’s magnetic field, weakens the life-threatening solar radiation, thereby maintaining the conditions for the existence of life on Earth. Presumably, life appeared on Earth about 4.25 billion years ago, that is, shortly after its appearance. Scientific evidence indicates that the Earth was formed from a solar nebula about 4.54 billion years ago and soon after it acquired its only natural satellite, the Moon. The only body known to man at the moment is the body of the Solar system in particular, and of the Universe in general, inhabited by living organisms. Sometimes referred to as the World, the Blue Planet, and sometimes Terra (from Lat.
