Breh, if you think advanced aliens have decided to communicate with humans through random patterns in random fields, 99% of the time in the exact same small region where particular pranksters just happen to live, then I don't know what to say to you.
I have some questions though:
1. Why are these crop circles virtually always in places that are super easy for pranksters to reach? Almost always near roads that allow for an easy getaway, almost always within a short distance from places where the circle pranking community is known to live, sometimes even in the same fields multiple years. Wouldn't aliens that could travel by air be a lot more indiscriminate in where they did their circles?
2. Why are these crop circles virtually always in places where people are known to prank? Virtually all of them are in wealthy English speaking countries, with over 90% in a small region of England where the pranks started, and the minority remainder mostly in USA, Canada, Australia, occasionally Israel. There are a few in Europe, especially in a small area in the Netherlands where the sole culprit (likely for all of them) has been caught in the act before. But they're almost never in South America, Africa, Asia....why is that?
3. Why did crop circles suddenly emerge as a common phenomenon in the 1970s? Reports of crop circles before that are extremely rare, and limited to very rudimentary circles that could be explained by all sorts of other things. Then in the 1970s, they suddenly started appearing like crazy, almost all within a small area in England. Then in the 1990s, they suddenly started becoming much more complex (coincidentally, just about the same time that people with computers could start using algorithms to draft their designs). If these crop circles were made by ET, then why wasn't there a single complex crop circle before 1980? Weren't the aliens already far more advanced than they'd need to be for such a simple task? Why does the complexity in the crop circles perfectly follow the advance of human tech?
4. With tens of thousands of these crop circles made, why isn't there a single video of it happening? People have security cameras, game cameras, ring cameras set up all over.....no one actually "sees" the UFOs doing it. But humans have been caught doing them.
Crop circle pranksters have admitted to it since the beginning, they've been caught in the act plenty of times, and there was multiple cases where believers claimed that a crop circles was "definitely" an ET one only to have the real human culprits emerge. The fact that there's a heavy subculture of crop circle pranking in a few regions in England, only occasionally copied in other similar countries, is well known. You have to be more serious with your ET visitation evidence.
In terms of the "Arecibo reply" specifically, it was clown shyt, such an obviously human-created message. They were so lazy that they did the reply right in Hampshire, UK (just happens to be where most of the crop circle pranksters live), and made almost the same message outside of obvious human-added changes. They stuck in silicon instead of carbon (a favorite theory of ET researchers is that ET life might be silicon-based), they replaced the human with a very typical "Gray" alien figure, and they altered the DNA slightly. Those are all obvious changes that a not-very-creative human would come up with.
The mic drop is that the Arecibo message was aimed at a galaxy 20,000 light years away, but the crop circle was made just 27 years after the message was sent. There's nothing there within 27 light years in that direction, it's empty space. So who replied? There wasn't even a solar system in any area that could have recieved the message by that time.
