Bradbury's omission of this explanation, however, like Shelley's in Frankenstein, indicates that the actual mechanism isn't the important bit of the story, rather being subordinated to the philosophical questions it brings up. While the actual scientific explanation for the aliens' invasion is never mentioned, it has something to do with the construction of some geometrical metal apparatus, if the items Mink takes from the kitchen are any indication. Being so young, furthermore, children apparently have heightened sensitivity to detecting other, higher dimensions, such as the ones the Martians (extraterrestrials, at least) use to communicate and travel. Only children have the imagination to look under bushes, according to Drill, and their extreme susceptibility to manipulation makes them perfect targets for the Martians. Instead of openly communicating with world leaders or descending from the sky with armies of starships, the aliens have opted for a more insidious, tactically brilliant approach: using the children of Earth. In the words of Drill, the Martian, Earth is 'impregnable,' entirely resistant to most typical forms of violent invasion.
