CROP circles according to conspiracy theorists are real and contain hidden messages from aliens or human time travellers, a scientist has claimed.
Dr Horace Drew, 61, who holds a PhD in Chemistry from Caltech, the California Institute of Technology, and worked for CSIRO as a molecular biologist, has been researching crop circles and aliens for 20 years. He also suggested that the mysterious phenomena are a method extra-terrestrial beings are using to try and peacefully communicate with the human race.
Skeptics say crop circles are most probably made by humans with some even trying to hoax the general public as pranksters Doug Bower and Dave Chorley did.
A huge crop circle in the shape of a swastika has been spotted in the Wiltshire countryside.
