Re: What do non-man made crop circles mean?

I have been looking into this for years and have yet to be convinced that the UFO crop circle phenomena are anything other then human earthling military technology.
If you look at the history of UFO's and crop circles you can plainly see that they have improved in appearance or sophistication that parallels our advancements in technology.
Most of the new crop circles now imitate computer enhanced so called sacred geometry.
Most of the UFO sitings I have viewed through videos or personally can or could be duplicated with modern military technology.
Also who is to gain from the threat of an alien invasion but the military and the powers that be.
This is an interesting subject but I would think with all the modern technology that modern man possesses that an alien presence if real would have been uncovered and made public by now.
