      The chemistry and physics from which created the primordial soup from which life arose on Earth are pretty universal. They won’t change from place to place or time to time. So the chances of forming a primordial soup and evolving life on a distant planet around another star are good. Whether that life is intelligent is another matter… I’d ask why would aliens want to come here anyway? Earth and our Solar System are pretty boring on a galactic standard!

      Single celled microbial life – it is possible. Life as we know it requires specific elements, water and energy and these requirements could feasibly be met on other planets – for example, we know that early Mars (billions of years ago) was a water rich planet that met many of these requirements.

      However, multicellular and intelligent life is less likely when we consider the number of evolutionary steps required to reach this point and the fact that mutation is random – there are no goals to evolution, the most successful organisms survive, meaning that intelligent life may not arise where there is life.
