Ken Tapping: We’ve all seen aliens. They are man-shaped, wear elaborate rubber and plastic makeup and move awkwardly, probably because the poor actor or actress inside can see very little through the eyeholes. They usually speak perfect British or American English, although sometimes a Canadian accent turns up. On occasion we encounter aliens who speak perfect French. Of course all this is just TV science fiction. Real aliens will be very different. Life first appeared on our Earth between 2.5 and 3.5 billion years ago. We are the result of a long and unique line of evolution. Apart from being moulded by the conditions on our planet, evolution has been redirected by various catastrophes. If we started again with the same conditions, we almost certainly wouldn’t end up with the same results. It is extremely unlikely that life on other planets would be anything like what exists on our world. Our sun and its planets formed some 4.5 billion years ago, presumably in the same way as we see new stars and planets forming today, with the collapse of a cloud of cosmic gas and dust. Space is filled with these clouds, and we can observe all stages of the process. This does not apply only to our galaxy; we see it going on in millions of other galaxies, out into space as far as we can see.
Among the first things to form after the beginning of the universe, around 14 billion years ago, were huge clouds of hydrogen. Stars formed from these clouds and obtained energy by turning hydrogen into other elements, such as oxygen, carbon and so on. At the end of their lives the stars returned their material to the clouds, so that after a few generations of stars had come and gone, the interstellar clouds contained all the ingredients needed to make planets and people. Empty space is a hostile place: a vacuum flooded with ultraviolet and other radiation emitted by stars. Any complex molecule would be destroyed as soon as it forms. However, in the densest clouds, the radiation is blocked out, and over millions and billions of years, the elements in the clouds have slowly combined into a veritable witches’ brew of chemicals, including water, ammonia, alcohol, methane, hydrogen cyanide, carbon monoxide and many others. When planets formed, they inherited a good portion of these chemicals, which became part of the atmospheres of those new worlds. QC
