When it comes to the life on earth several conditions need to be satisfied in order to live on this planet.
● the very first thing that is basic is the presence of air that we breathe. Air is is one of the major components which is responsible for life on this planet as it has the perfect balance of carbon dioxide and oxygen along with other gases.
● second important condition is the presence of a perfect temperature. As can be seen on the other planets that the planets which are very close to the sun have very high temperature and are not suitable for living and the planets that are very far away from the sun are very cold to live on.
● third is the presence of gravity on a planet which is responsible for letting us stay intact and in contact with the Earth surface so that we do not Bounce into each other.
