Why is earth able to sustain life and other planets cannot?

Answer 1

It has liquid water on it. That is standard answer you will get from science as we know it now. It is quite possible though that there is some liquid water on all planets and moons if some in only very tiny amounts.

Since life has now been found several miles below the surface of the earth it is conceivable life is hiding there on many of the rocky planets and moons. Also on the icy ones, there is usually an ocean under the ice. On a planet like Titan where there is liquid methane in lakes on the surface, an entirely different life form pattern may exist...

Answer 2

This is mostly conjecture by scientists but they theorize that only Earth has life because it is the only planet with an atmosphere containing adequate oxygen and carbon dioxide and the only planet containing liquid water.

Animals of the land and the water cannot exist without oxygen.

Plants cannot exist without carbon dioxide.

And neither animals nor plants can exist without liquid water.

Answer 3

Earth's ability to sustain life is due to a combination of factors, including its distance from the sun, presence of liquid water, and a protective atmosphere. Other planets may lack these conditions, making them inhospitable for life as we know it.

Answer 4

The planet Earth is containing life because of its atmosphere.
