"according to Dr Drew, a number are legitimate and contain puzzles that can be decoded and linked to time travel and alien life."

"During the early to mid-2000 crop circles became images of discs with binary messages, alien heads and even a message back from extraterrestrials from the message we sent into space in the 1970s.
Experts in the paranormal and crop circle topic became very excited as they realized that the patterns were displaying some kind of hidden messages.
Dr Horace Drew studied messages hidden in crop circles and after realizing that some (not all) circles are hoaxes, the genuine ones included hidden binary messages. Drew understood the binary coding and claims to have decoded the messages."

"He said some of the decoded messages read: ‘Much pain but still time. Believe. There is good out there’; ‘Beware the bearers of false gifts and their broken promises’; ‘We oppose deception. Conduit closing’.
Dr Drew has developed at least two theories as to the purpose of the circles by reading their “advanced (version of) binary codes”."

"According to crop circle researcher Lucy Pringle the pattern contains a hidden code for a complex mathematical equation called Euler's Identity, considered by many to be among the world's most beautiful and elegant theorems."

"This long term threat was only shared on a need-to-know basis, and emanated from World War II events involving Nazi Germany’s advanced technology programs. Events which Nelson Rockefeller and Kissinger were deeply involved – the existence of extraterrestrial life and technology."
