Scientists agree that the evolution of intelligent beings like us is an event unlikely. This is because there are a number of events that must occur on the table for this event. Let’s look at what it is. 1: a planet like the Earth unless the life forms that would be different from our own, rather than anything invented by man’s imagination is possible that extraterrestrial life first requires a planet like Earth – and that someone with a climate not very hot or very cold It consists of both liquid water and rock, but some people believe that the Declaration Angels Nephilim some think that the Nephilim sons of God and they can maintain the kind of climate. 2: The Rise of bacteria and single-cell bacteria are the dominant form of life on our planet for three billion years. It is the first step to intelligent life. How exactly can live something comes from nothing, and we do not know, but we know that an essential first step. March: the complex and specialized cells, and this is the next big thing – more complex and specialized cells that allow life forms to complex multicellular development. One-time single-cell micro-organisms, and this may be a step is inevitable, given enough time. 4: intelligent life with the language of complex, and this is the last step on a long road – intelligent life with the language of complex, and cultures, and eventually technology. Again, the presence of these animals and inevitably a complex one time, but it will take a long time. The astronauts were old and present, and all the previous steps should have happened, and the last three in the life of this planet, where he spoke.
