Just saw a documentary on TV that went on and on and was all very
interesting showing all the reasons why crop circles could not be all
man-made no matter how creative and technologically equipped the
fraudster was. Many experts came on to reinforce the view that a yet
undiscovered force was at work,i.e geo-electrical forces, natural
lights from the heavens descending on earth with
some sort of focussed energy capability etc etc. However the show
never dealt much with those circles that are known to be fake and/or
man made or indeed any alternate experts who could probably just as
easily show that ALL of the circles and formations could be shown to
be formed via  very creative and smart humans.
 Can someone direct me to a site or reproduce the evidence as an
answer that I can read on such an alternate view.

Don?t have the sources handy (I am sure someone will come up with
them), but I have seen two documentaries exploring and documenting
crop circle creation by those individuals (humans, not aliens) who
made them.  One actually showed, using time lapse photography, a group
of four men who, over a span of time from 2:00 a.m. to 6:00 a.m.,
constructed a beautiful and elaborate crop circle in a corn or wheat
field using nothing but ropes and stakes and boards and their hands
and feet.  Sure, they had to design it out first on a computer, but
once they got to the field they just went in there and drew it. 
Nothing mystical at all.  I thought this whole thing by now had been
fairly well debunked given the numerous admissions by the actual crop
circle makers and this documentary I saw that showed the actual
formation of an extremely intricate pattern.

Here are a couple of interesting articles:

I saw the same documentry and what was really interesting was all the
people who came out during the day and "proved" that it couldn't have
been done by humans.

Thanks to all and yes Pink One I read your contributions in their
entirety; most interesting.
