Of the many unexplained phenomenon which continue to puzzle scientists and laymen like, the corn circles of Southern England remain one of the most mysterious. These perfect-formed circles, which, when they see from the air appear to have been inscribed with an enormous carving tool, seem to be a part of a significant message; so far, however, nobody managed to decipher them, and it is doubtful if anyone will ever be able to. But the main question – how the circles came to be there – is just as far of being solved. Although several people had come forward claiming to have made the circles themselves, scientists declare that it would be impossible for even a large group to create shapes of such precision on so a large scale. These circles have become one of the strong arguments in support of the existence of intelligent extra-terrestrial life forms.
