well but if they sent that alien formation with the disc in binary that encodes ascii to plain english text then if the crop circle is real and done by them, then they do undersand. since the laser is emiting binary codes too...

and the arecibo message we sent and then recieved "their" version is also binary, so they show to have high knowledge about everything and math and binary and their tech can understand ours, though they can do better, but then we can't understand.

PS: IF those are real cropcircles, but if this is fake, i will feel very mad with the guys done that.
