Answer 2

The factors that made life possible on earth, are as follows -

• The earth is in suitable distance from the sun, not too far and not too close. This helps to build an overall suitable temperature condition, by avoiding extreme hot or extreme cold,conditions. This is necessary for formation of life. Availability of life is mostly unavailable in extreme hot or extreme cold planets.
• The earth has properly developed atmosphere which is very important factor behind the formation and sustaining of the life in our planet.
• The presence of ozone layer in our atmosphere is another great factor, as it resist the harmful radiation from the sun and sustains the life on our planet.
• Availability of different types of necessary resources for sustaining the life. (eg. good climatic conditions, food materials, other necessary resources etc.)
