dude, this stuff is serious man don't you know it. I mean, let me find you the documentary of how some aren't man made. They actually show how the plants have been burnt right above the roots.

Upon casual inspection of the comments for that video, I saw that it was noted several times that the video producer later admitted the video being fake.
You can read up on it and find the article yourself.

You should investigate a bit further before taking things at face value.

Edit:
Guess you did. lol... as you've quickly taken the video link out of your post.

You just wait. There is a great pumpkin Charlie Brown!

ok, you got me there. Or i got myself, lolol.

Humans do not make these.

So let me get this strait... aliens said f*ck you physics and traveled millions of lightyears just so that they could leave not-so-obvious signs on Earth? If they wanted to tell us something, why not do something humans couldn't easily replicate? You traveled across galaxies but you can't think of a better sign that you came then a circle in the dirt or a pattern in a crop?

I'm actuall pretty sure that humans made all of those.

The ones that are apparently genuine usually entail circles, generally many circles criss-crossing each other, and cut into the crops at different heighths. From what I understand, they only take a couple of seconds, because they're using holographic projections.

The aliens aren't coming here hoping we'll turn them into deities. They genuinely want to give us a message. These are spiritual messages. It's believed that many of them are operating on higher dimensions, so I doubt they'd be so vain as to go through a wormhole in another galaxy, or possibly different dimension just to come here and inscribe pictures of themselves.:rolleyes:

i agree with this, and this is the same think Michio Kaku always says, but i'd like to know how humans make them, and how long it takes. because until i have proof i am not buying it.

just google 'how are crop circles made'. If we can split the atom, and virtually replicate the speed of light with modern technology, I'm pretty sure we can make those circles. We can't make the ones like Alton Barnes 1990, Barbury Castle 1991, The Pentagram 1993, The Labyrinth 1994, Silbry Hill Koch Fractal 1997, West Kennett Square Fractal 1999, Milk Hill and the Angel 2001, Crooked Soley 2002, The Towers 2006, The Temple 2007, Barbury Castle, PI, 2008, because I believe all of those appeared overnight.

Sorry, I would have posted pics, but that always seems to give me problems, that most recent is the best, and the one that's already been sighted this year is astounding: I'll get a link to it in a sec.....damn can't find it......it was in June of this year, anyways the coolest ones are:

Stonehenge Ribbons 2002
Milk Hill 2001
Stonehenge 1996

I got these from the book Crop Circles: The Bones of God. It's a good book. It also goes into a lot of the numerology associated with # of circles in each work, significance of some of the angles, and the sacred geometry, and he also explains how it would be pretty much impossible for humans to make them. You should really check it out.
