Radiation has existed on Earth since its formation around 4.6 billion years ago. Natural sources of radiation, such as cosmic rays from space and radioactive elements in the Earth's crust, have been present since the planet's early days. Early life forms evolved mechanisms to cope with this background radiation.
eff the time in wich life first evolved on earth!!
The first human on Earth is believed to be Homo sapiens, who evolved around 300,000 years ago in Africa. There is no single identifiable first person to have arrived on Earth as humans evolved over time.
The most common radiation on Earth is non-ionizing radiation from the sun, such as visible light, infrared radiation, and ultraviolet radiation. These forms of radiation are generally low in energy and do not have enough power to ionize atoms or molecules.
The Earth itself does not emit ultraviolet radiation. Ultraviolet radiation primarily comes from the sun, which emits different wavelengths of light including ultraviolet radiation. When the Earth is exposed to sunlight, it can absorb and reflect this ultraviolet radiation.
Yes, the Earth does give off radiation in the form of heat. This radiation is primarily in the form of thermal infrared radiation emitted by the Earth's surface in response to solar energy absorbed during the day.
To Much UV Radiation! :)
They didn't come to earth they evolved here

Impossible to say. Comets have been striking the earth since before life evolved on the earth
Cat didn't "come to Earth". They evolved here about 25 million years ago.
there's no radiation
Clarify what you mean by "evolved".
The Earth emits terrestrial radiation constantly, but the amount of radiation emitted depends on the temperature of the Earth's surface. Warmer objects emit more radiation than cooler objects, so the Earth emits the most terrestrial radiation during the day when it is exposed to sunlight.

Yes, long-wave heat radiation is given off by the Earth as it absorbs short-wave radiation from the Sun. This process is known as the Earth's energy balance, where incoming solar radiation is absorbed by the Earth's surface and later re-emitted as long-wave heat radiation.
