It's often a really tough question to explain why something isn't.
A better question might be: What is it about Earth that makes life possible here ?
But it really does make you stop and think sometimes, doesn't it !
No life has been detected except on the planet earth.
not that we know of. but the 8 planets we have, all of them dont except earth has life.
We do not know. So far, organic molecules have been located on planets and in distant stars, but this is not proof that organic life exists there.
As far as what we know today, there is no life on any planet anywhere, except the Earth.
All planets rotate. Even earth.
Life probably does not exist on any of the known planets (except earth). But if life does exist on one of those planets, it would probably be on Mars. Venus is way too hot, Mercury does not have an atmosphere, and the other four planets are made up almost entirely of gas.
The inner planets, except earth, are made up of rocks. They have a hard surface. The earth would be one of these except we have water. The outer planets are gas giants and do not have a solid surface.
All of them, except for Earth.
All of them except Earth and Uranus.
All except earth and venus.
All, but earth.
Earth is a planet and there's life on it.
