Is there a way to prove that crop circles are extraterrestrial?
Question Date: 2018-10-17
Answer 1:

First of all, there is no way to prove that a hypothesis is correct. This is a widespread misunderstanding which educators should probably spend more time correcting.

Evidence (i.e., results of experiments or tests) can provide support for or refute a hypothesis, but not definitively show correctness. While the results of a particular test may be in line with a hypothesis, repeated tests or a different test may show that a hypothesis is wrong.

As in this article, the hypothesis of all balls in a can being white is supported (but not proven) by pulling out one that is white, and is refuted (shown to be wrong) by repeating the test and getting a black ball.

That being said, there is evidence that crop circles are not of extraterrestrial origin. For example, the creators of some of the first modern, complex crop circles admitted making them, and subsequent circles are known to be copycats. Some simpler crop circles (e.g. plain round circles) are quite likely made by natural weather phenomena similar to dust devils.

Answer 2:

That's bad science, but I've also seen the same bad science in grant proposals asking for lots of money. You want to test the hypothesis [the idea] that crop circles are extraterrestrial. Then you are being a good scientist, with your mind open to both Yes and No answers. That can be hard to do - to keep your mind open to both Yes and No answers. We usually want one answer to be true and not the other answer.

Then you have another problem, if you want to convince scientists that crop circles are extraterrestrial. You need to have an extraordinary amount of evidence - lots more evidence than if you wanted to convince scientists that crop circles come from things that happen on Earth, because that's easier to believe.

An example of this is that it's easy for people to believe that you saw a horse, but it's hard for people to believe that you saw a unicorn. So you need to have lots more evidence that you saw a unicorn, and that's hard to get.

Answer 3:

All crop circles that we know of are human-caused.
