No. There are life forms on Earth that can survive in extreme conditions where humans can't. The environment on Earth when life first emerged would have been toxic to us. If other planets have these conditions then they may support life. The main ingredient scientists believe to be necessary for life is liquid water. Earth is the only planet known to support liquid water on its surface, but we know very little about the planets that exist outside of our solar system. While it is unlikely that life exists on any of the other planets in our solar system, we have no way of knowing with current technology if planets in other solar systems support life.
Very probably
Because the other planets just don't have the right conditions for humans and animals
Other planets can't be inhabited by humans because they can't support life.They don't have an atmosphere with enough mixture of right gasses to sustain life.Other planets also don't have simple water in a consumable form.
No, the Earth is the only planet with Humans.
nothing would happen to other planets if the world ended because the planets are so far apart that the explosion wouldnt reach too other planets and take my advise. the world wont end right now because since when humans exist, the world is still young.
no. no humans have ever been to any of the other planets.
yes
There are humans.
You can stand on Pluto and mars because they have a solid surface. You could NEVER stand on any of the other planets. They are made of gas, If you were stupid enough to stand on one of the other planets you would die once you get on it
Other planets other than earth is put in the solar system for humans to explore and do researches on them.
Humans can live on the planet Earth. Other planets are unsuitable for our existence unless new technology was able to assist humans in harsh environments.
it would not be helpful because there is no air so you cant breathe
