It tells the story of England being invaded by Martians. from The War of the Worlds by H. G. Wells. No one would have believed in the last years of the nineteenth century that this world was being watched keenly and closely by intelligences greater than man's and yet as mortal as his own; that as men busied themselves about their various concerns they were scrutinised and studied, perhaps almost as narrowly as a man with a microscope might scrutinise the transient creatures that swarm and multiply in a drop of water. How does the author's description of Mars impact the plot of the story? It emphasizes the reasons that humans should have anticipated that Martians would invade Earth. It heightens the contrast between what the people of Earth want and what the Martians want. It implies that Martians would not have left their planet if they had not been forced to by humans. It shows that Earth and Mars are so similar that Martians would feel at home on either planet.
