It might not be the only planet with life. Life could exist on planets outside our solar system. There is just no way of finding life on one of these planets without actually going there. There is even a slight possibility of life on Mars.
The only known planet to support life as we know it is the one you and I are on, Earth.
Only one planet has confirmed life: the Earth.
So far, Earth is the only planet we know of that has intelligent life.
EARTH the planet that we live on the only one that can hold life .
Earth is the only one we know about.
Earrrrrth is the thirrrd closest planet Eva
The only planet that we are aware of is the earth. So far we have discovered no life anywhere else
What is unique is that it has beings who ask questions starting, 'what is unique about . . . ?'
In my opinion Earth is the best planet, since it is the only one that is known to support life.
earth. that is the only one we know of currently althoug water has been discovered on mars.
Who ever said Earth was the only one, what about other unexplored galaxies.
There is a major difference from our planet and the other which is that our planet is the only one that is habitable for life
