Earth is the planet with the most life. Some people believe we are aliens and evolve from a creature called archea. Archea can breath iron and can survive extreme temperatures. They can go for millions of years without food, and live in the hot springs of Yellowstone National Park. Their characteristics do make it possible that if the came from another planet that was destroyed, they could have been inside of a meteor for millions of years and crashed on Earth (archea is microscopic).
The Mars Rover also discovered water on Mars. To survive, creatures must have a water sources. If there were aliens on mars, they would have to be microscopic.
No, Earth is not considered an organism. It is a planet that supports various forms of life but is not a living organism itself.
Another name for the Earth's atmosphere is "air." It is the layer of gases surrounding the planet that supports life and protects it from the harsh conditions of space.
The Earth's atmosphere helps regulate the planet's temperature by trapping heat from the sun, creating a habitable climate for life. It provides the air we breathe, containing essential gases like oxygen and nitrogen required for respiration and sustaining life. The atmosphere also protects Earth from harmful solar radiation and meteoroids, creating a shield that supports life on the planet.
The troposphere is the only layer of the atmosphere that supports life. It is the layer closest to Earth's surface and contains the air we breathe, as well as the majority of Earth's weather phenomena.
The Earth is the third planet from the Sun in our solar system. It has an atmosphere that supports life, abundant water in liquid form, and a diverse range of ecosystems. It also has a solid surface that includes mountains, oceans, and continents.
Earth supports life, because it has oxygen.
Earth
The planet that supports life, and has an ozone layer. Unless there's another world with life, instantly it's Earth.

Earth is called a life sustaining planet because it has life on it, and is currently the only known planet that supports life.
At the moment, as far as we know, the only planet suitable to support a diversity of life is our Earth.
Earth is the only one we know about.
It is the only planet that supports life. (As far as we know)
It is possible,the universe can't be endless and only earth supports life,it'll be waste,there is a planet out there that supports life
We do not know of any other planet with a sustainable atmosphere that supports human life.
Earth is the most habitable planet in the solar system, which is why there is so much life on it. As far as we know, no other planet has life on it. Mars could possibly support human life, with supports to help them.
