Many exobiologists believe it is likely there is life off the earth, however, none has so far been detected. There has been, and is, life off the Earth. Humans and other organisms delivered into space and nearby celestial objects by space craft.
because plants give off oxygen and support life for us and we have water.
No, it doesn't help the Earth. It only protects all the DNA-based life on its surface and in the air above it. The planet itself is not helped by whether or not life is present. If there was no life on Earth, it would be very different. Would the Earth be better off with no life? I don't think so!
Yes, but it is a long way off
All life one Earth depends on plants for survival as only plants can make their own food. If plants died off, most other life on earth would die off as well.
then plants will die and oxygen will be eliminated from earth and life as we know it will be over
Life is on earth of course
Because we are, to the best of our knowledge, the only planet with life on it, certainly in the "near" neighbourhood. As an island is surrounded by sea and totally cut off, the earth is by space.
Armageddon is defined as a catastrophic event which will lead to either the destruction of Earth or the extinction of life. Another word for it is apocalypse. For example, an asteroid shattering Earth or a viral outbreak killing off all life. It is certainly possible.
life on earth just pure stupid
You stay on the earth. Without it you would fly off into space and die because the atmosphere will be too thin to sustain life.
about 60 or 70% of life species plus humans will died out when if the asteroid apophis when if hit the earth that asteroid is size of manhattan same size which killed off the dinosaurs
Walk off the Earth was created in 2006.
