...Boy! You aren't the only one, kiddo!
This is just about the best that I can verify, given
your question. Remember, we are--as citizens of the
U.S.A. and MOST Western countries--at the LOWEST
"tier" (level) of information receivers. I would very
much wish it were otherwise, because I have an insatiable
curiousity about these things! As an example--and this
is NOT an effort to puff myself up--I've got 3 college
degrees (from real Universities--not just "box-top"
send-in-your-lessons kindof "degrees," either!)....
have been a "career" college student (i.e.,
education is what I do...) and my hobby is RESEARCH!

That said, I was AMAZED that I came across the video
on page 1 of this thread which gives the information
that the STATUES OF EASTER ISLAND have carvings on their
backs which indicate a STAR SYSTEM is associated with
those who carved them. I've never heard about that....not ONE SINGLE WORD and this is my passion! So....what you
and I can find out--at our level--is limited information.
(BUT....DON'T STOP SEARCHING!)
Here is a follow-up video to your question. Supposedly,
the "CD"-looking disk in the crop circle was deciphered
and there was a message!

[link to www.youtube.com]
They put it on the screen in the video, but basically
the message is from an alien race, silicon-based and
smaller frames than humans--star system was probably included, but NOT in the video--They are saying
"There is much good "out-there"--to not despair. They
OPPOSE deception and lies and ARE aware of the
planet's situation." That's as good as I can give you
there's more on the video!
Interesting stuff, I'd forgotten about all of this as
it began to be made public in 2001!
Nice catch!
Cheers!
