Life is impossible on planets other than the Earth because the Earth is the only planet in the solar system and in the known universe that can sustain life. In Mercury and Venus, it is too hot for life, and there is a lack of water for life, and in Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto, it is too cold to sustain life. Earth is great because it is just close enough to the sun so it's not too hot, yet not too cold. It's just right. Plus we have water on the Earth, (h20), or two hydrogen molecules bonded with one oxygen molecule, but not any "real" water has been discovered on other planets, and all living things rely on the warmth of the sun and water to survive. Hope I helped!

Because we have the evidence of early life such as fossils and other things
Nobody knows for sure, scientist are still debating whether or not there is an existence outside of our boundaries.
Because other planets don't have an atmosphere, oxygen, food, and water and we need those things to survive
because it so fesh and ect...
Scientists say that life can be expected to have evolved on other planets, wherever the environment is not so hostile that life can not be supported. They say that in this vast universe there must be many such planets that can support life and that some are likely to support intelligent life forms even more advanced than humans. Whether we believe that our God created the life on other planets is a matter of human faith. No doubt any intelligent life on other planets will never have heard of Earth's gods.
You can only survive on Earth but no other planet.
The earth orbits the sun between the planets Venus and Mars. The other five planets are farther out than Mars. The closest earth gets to Venus is 23.7 million miles. The closest earth gets to Mars is 36.4 million miles.
Compared to some other planets in the same galaxy, yes; it is actually fractions of the size of other planets in this galaxy
This is because there is absolutely no trees on other planets.Mean while the trees are the propagators of oxygen on earth.hence the absence of oxygen on other planets.
because there is no air and the other planets are far away to visit.
it was very difficult to understand the retrograde motion of other planets if earth was considered to be at the center of the solar system but it could be easily explained if earth is considered to revolve around the sun along wit other planets. So explanation of retrograde motion of other planets made them realize that earth moves around the sun.
The other planets do have gravity.
No. Earth's magnetic field only affects earth, not other planets.
Of course, with properly pressurized suits and sealed, pressurized environmemts. There are no known planets where humans could live in the open as they do on earth.
Since no one from Earth has visited another planet, and we have no indication that there is anyone on the other planets, Earth does not help other planets in any way. Why do you think there is something Earth does to help them- whoever them is.
yes, the earth and other planets revolve around the sun
Earth and the other planets are mostly made of rock.
Earth and the other planets are mostly made of rock.
The other planets actually do have seasons.
Studying the earth helps scientists to understand other planets since the earth is part of the solar system. Scientists use the features of the earth to compare them with what other planets hold.
