Because Earth happened to meet all of the criteria necessary for supporting life which eventually evolved into humans. Now that we are here we will continue to reproduce until we no longer can. To say that we are here to worship a god is to assume that there is one. Scientific answers please, save the spiritual ones for the people who are asking why there is life in general and not asking about a species and a specific location.
Given the immense number of planets in the Universe it would be unsupportable to state that "only the Earth" can support human life. In this solar system no other planet has surface conditions which would allow exposed humans to live. This does not preclude humans living in contained communities or in a terraformed environment.
it is used in tv,live telecast, to show pictures of earth and other planets etc......
Quite simply, this is any space vehicle that does not have a live crew of humans or animals on board. All communications, military and meteorological machines that are orbiting the Earth are unmanned satellites, as are the probes that we have sent to other planets in our Solar System.
No, it is not for only humans. It existed long before humans appeared and will exist long after we are gone; in that time, it has, is and will support hundreds of millions of other types of organism.
The biggest reason is water. Astronomers think maybe there really may be traces of water or ice on other planets, but Earth has an abundance, perfect for us. Also, many other planet's living conditions are not suitable. Some planets have EXTREMELY hot hot hot or coooollllddd ccccoollllddd weather that we could not live through. There is not fertile soil or animals to eat (we probably wouldn't be eating aliens :P ). And atmospheres aren't as nice, no substantial protection from the sun's rays and gravity not as strong. There are also some more detailed answers but these are mostly the main ideas why the Earth support life when other planets cant.
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.
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.
Very probably

We live on Earth, aliens live on Pluto, Mars, and other planets like Jupiter.
The basic requirements of human beings are air and water, if these two things are present on any planet, then it can be possible to live on that, but unfortunately our astronomers did not able to find any of such planet, but in future it can be possible. So hope for the best!
It depends!
Mars is the next best option in the future.
No one can answer this question as we do not have any proof of whether they do or don't. Some believe that there are planets out there that are the right distance from the sun have the same size sun and planet as ours and have similar atmospheric conditions. If there are such planets, it is possible that a human or human-like species could live and thrive there.
Humans can currently live on Earth, as it provides the necessary conditions for human life such as oxygen, water, and suitable temperature. There are ongoing efforts to explore the possibility of living on other planets like Mars, but at present, Earth is the only known planet where humans can live.
We live on earth because it is the only planet that can support life. Other planets are too far from the sun whereas others such as mercury are too close to the sun. Earth has just the right stable temperature for human, plant and animal life.
Us humans are rather finicky about the conditions we can live in. It can't be too hot, it can't be too cold, there has to be water to drink and air to breathe. The gravity has to be about what it is on Earth and so on... As far as we know at the moment no, as there are currently no planets that we know of with the necessary temperature, gravity strength and atmospheric composition for humans to survive. We can only know this about the planets in our solar system however.
