Do Aliens make the crop cricles?
There is lot of information available on crop-circles in the format of video and articles, so I will not say too much here except one thing. If they want to get our attention so badly, why haven't we see a crop circle in front of the 'White House' lawn, or 'Washington Memorial'? Let's even forget United States. Why haven't we seen any crop circles in front of some of the most recognizable places in the world that is heavily guarded by security, after all, no security can destroy aliens, right?
Once you ask this question, you may find the answers easily.
That's it. That's all there is to this article.
In my Sci-Fi book Kyirux trilogy, I do use some of the crop circle theory, especially in the third part 'The White Gates'.
