No one knows for sure if life exists outside of the planet Earth. There are some human beings outside of the planet Earth on the International Space Station which is in orbit about 250 miles above the planet.
No there are other forms of life that share the planet with human beings.
Because if the temperature was different human beings would not have evolved.
Earth is the home planet of human beings. No one discovered it. Humans have always lived here.
Earth has atmosphere. It helps in maintaining a perfect temperature to live.
As far as we know, the only planet that human beings have walked on is the planet Earth; we have also walked on the moon, but that is a satellite, not a planet.

It is because of the natural resources our planet provides. Things like water, food sources, and oxygen are essential for human life and are provided by earth.
No because Earth is the only planet that has life and other planets are too near and too far from the light and atmosphere has to be oxogenNone on this planet have gone out and colonized other planets. If there are any humans for any reason out amongst the stars not of our world, we have not yet met them.
Nothing. There is no evidence of life on Mars. Considering that spacecraft from the planet Earth have landed on Mars, we human beings from Earth are the Martians.
Earth is the only planet human beings live on. If there are other planets on which we can survive, they will need photosynthetic life forms to liberate significant amounts of oxygen into their atmospheres. Free oxygen readily combines with other elements--without life it is unlikely concentrations of the gas would be high enough to support human beings. Bats, maybe. Bats can survive in high CO2 atmospheres. Possibly we may engineer humans who can survive in a wider range of environmental conditions than we can now.
