Answer» s unique in the Solar System as being the only planet which is able to support life in all its forms - from basic living micro-organisms to highly sophisticated and intelligent human beings. 1) WATERWATER is believed to be the most important CHEMICAL NECESSARY for life. It contains the oxygen needed for life. Other liquids contain poisonous elements. Water doesn't burn skin (like liquids containing acids do), it is drinkable, and it allows life-providing molecules to move around easily.2) SunPut simply, if there was no SUN, there would be no life on Earth. Technically, Earth probably wouldn't exist either! Because of Earth's ideal distance from the Sun, it receives the perfect amount of heat and light to ALLOW life to be created and to support it.3) ClimateEarth has a suitable climate. This is caused by the moderate amount of carbon dioxide in the planet's atmosphere, which is constantly refreshed whenever there is a volcanic eruption |
