I think that <span>Stonehenge was built by aliens. Because it consists of big stones and stands in the middle of the field. Humans didn't have any opportunities and resources for building it. They couldn't move or turn such big stones. A lot of people thinks that Stonehenge was built on the abnormal place. But how could the ancient humans know that it was the abnormal place? It was impossible for them. But a highly developed race could build it. So the best explanation is that Stonehenge was built by aliens.</span>
<span>As a child I often dreamt of travelling in time to see how people lived centuries ago and how they will live in the future. There are many films and cartoons about time machines and I wouldn’t mind having one myself. Generally speaking, it’s a mysterious and non-existent device for travelling in time. You can read about it in science fiction books. Although it’s almost impossible to build this device, there were several secret experiments held in Philadelphia and New York during the 20th century. Various science fiction writers have tried to describe this machine. One of the first writers who described the time machine was Herbert Wells. Some parts of his imaginary machine were made from nickel, others were ivory, while the details were carved from rock crystal. There was a special saddle for the Time Traveler to sit in. The machine operated on the motion along the time axis. The only difference between the time and other dimensions is the fact that our consciousness moves over it. Other authors described the time machine as a portable device which could fit in a suitcase. It could be self-adjusting and travelling through the tunnel of the infinite past. In a fantastic story, written by brothers Strugatsky the time machine takes the form of a bicycle. </span>
