Our planet is the perfect distance from our sun to receive enough light to keep water in a liquid form, our atmosphere has a well balanced amount of Nitrogen, Oxygen, Carbon Dioxide and other gases to support life and trap heat within the planet. Our planet also has water, a very important 'ingredient' for life. It is also a 'rock' planet not a gas planet and has a strong enough gravitation pull to hold on to our atmosphere, without this gravity the gases in our atmosphere would drift into space. Which is why Mars's atmosphere contains a very little amount of Oxygen, it when into space over millions of years. All other planets we have seen in our galaxy do not have the requirements for life, they are either too hot, too cold, too toxic, etc. And the odds of a planet meeting these requirements are astronomical.

There are several factors that contribute to Earth being the only planet known to support life so far, including its position in the habitable zone of our solar system, presence of liquid water, and diverse array of elements essential for life. Other planets may have conditions that are not conducive to supporting life as we know it.
