1. The Truth About Aliens...
Do they exist?

2. Signs or Hoax?
Crop circles is the name given to they geometrical shapes that sometimes appear in farmers fields.
Some have stated the cause of these shapes may be from ball lightning or vortices of wind; however these natural cause wouldn’t likely produce the shapes found in the fields.
The earliest crop circle dates back to the late 1600’s.

3. An Answer?
In 1978 Doug Bower and David Chorley, from Southampton, England, were said to have started the crop circle phenomena.
Doug Bower and Dave Chorley made their crop circles using planks, rope, hats and wire as their only tools: using a four-foot-long plank attached to a rope, they easily created circles eight feet in diameter. The two men were able to make a 40-foot (12 m) circle in 15 minutes.

7. What do we do with the information we have?
What do you think?

8. Evidence...
To date, life has not been confirmed on any where else in space other than on Earth. Everyone is entitled to their opinion. The only answer that is factually correct is "maybe". It is impossible to prove the absence of something until there is evidence. Until there is evidence proving the existence of extraterrestrials is uncovered, the answer will remain closer to "possibly" than "probably".
