Haven’t you often wondered whether there was some form of intelligent life living in the stars? Scientists have been trying to solve this puzzle
for many years. There are organizations like NASA and SETI that are focusing their technology and research on detecting new planets and solar systems that are suitable for human life.Some people believe that life occurred on earth by accident, and that the random events that caused it will never occur again. According to them, there are no chances of life being found on other planets. Others argue that life evolves naturally under the right conditions, and that if these conditions occur on another planet, life can exist there too.
While working as a radio astronomer at the National Radio Astronomy Observatory in Green Bank, West 
Virginia, Dr. Frank Drake worked out an approach to find out the possibility of other civilizations that may exist in our galaxy. The Drake Equation, as it has become known, was first presented by Drake in 1961. It lists specific factors thought to play a role in the development of civilizations. From these factors, the Drake equation tries to estimate the number of planets that exist with intelligent forms of life.The Drake equation is quite a difficult equation to solve. So, maybe when you are older, we will give you the equation, and let you try to solve it
