The first part of this question has been thoroughly answered. However, the second part comes from an incorrect premise.

We can live on other planets. It's just that we need a very large amount of technology and supplies in order to do so. Currently, the cost of this support is too large for us to feasibly establish a colony on another world, and there are no locations we have yet discovered which do not require extensive life support just to get there, let alone to live there.

Terraforming is one procedure that might circumvent this. Terraforming is the act of altering a planet's ecosystem in...

The reason we live on Earth is because all the other planets are inhabitable, and Earth has the food, water, and oxygen we need to survive.

Yes! You took too much space.

Because we haven't yet discover a habitable planet like earth, and by habitable  I mean, not too far nor too near to the sun, the air is breathable and stuff like that

It was not our wish to live on Earth. The earth was a deadly place to ive billions of years ago, it ws a big ball of fire and mercury. Slowly and gradually it cooled down but there was still no sign of life. A asteroid from somwhere in the space crashed the Earth and rhis led to life formation on Earth. We would not live here if there was no oxygen and the reqirements to survive.

 

ITS A BIG LUCK!!

 

And we don't live in other planets because there is nothing to support life.

 

 

But now we have become very modern, every thing is possible for us now. Scientists are planning to explode carbon-dioxide bombs to grow plants on other planets but not in the gass giants especially in the mars and the moon. But there place are asteroids prone area. In a few decades I think humans will rule the RED PLANET.

 

But I want to go back to my sweet home Kepler 22b.

Oh! Thats really silly! because this is a habitable zone, everything is there to be alive.

 

 

U R sinior to me but U don't know more than me.

We can live on earth because there is breatheable air. The earth also has enough water and food for us to survive. there is  gravity and loads of nutrients.

The Earth is set at the right distance from the Sun. This makes life possible for humans because it is not freezing like on Venus and it's not so hot like on Mars. On the Earth there are proper terms for life to exists.
