Lists various factors which are responsible for life to exit on planet Earth
Answers
Earth is often referred to as a Goldilocks planet. This has traditionally been connected to Earth's proximity to the sun allowing liquid water to exist on its surface. In fact, that assumption and some others led to something called the Drake Equation developed in Greenbank, West Virginia in 1961. It was a complex equation that calculated the number of planets in orbit around a star at the ideal distance for the sustained existence of intelligent life. The number of planets postulated based from the Drake Equation were 1000 to 100,000,000 in the Milky Way galaxy. More recent data from Kepler has put the estimate to around 12-17 billion Earth like planets in the Milky Way.
It may be true that billions of planets or more are in this "Goldilocks" orbit but what kind of life are we talking about and how are we defining intelligence? Bacterial, single-celled organisms or complex and diverse organisms with cognitive intelligence? In order for an advanced species to evolve and emerge as an intelligent, cognitive being such as humans - numerous other Goldilocks factors need to occur. It's not just about the water. Fortunately for us, we have that advantage. Here are the top 15 Goldilocks factors that make life on Earth as we know it possible.
