Indeed, all of the aforementioned devices would allow individuals to create these patterns quickly and with much precision. Similar designs can also be made by using ropes and boards to lay the vegetation flat. Such simple tools were the devices utilized by the earliest designers, whose patterns were a bit less precise. However, modern artists (and pranksters) have a host of tools and new technologies at their disposal. Unfortunately, this only increases the conviction of those who claim aliens are responsible, as they assert that humans could never make such huge patters with this amount of precision in such a short time. And even when it is proven that a specific design could have been created by using measurements, tools, and basic design skills, the deniers cry, "you don't have proof that every single crop circle was created by humans." Scientists have not measured and marked and researched every single crop circle in order to prove that each one could (in fact) be created by humans. But fortunately for us, that's not how science works. We have evidence which proves that humans could make these structures; we have no evidence of aliens. We also have no evidence that an invisible and radioactive pink bunny is making the formations, or the devil, or God, or Zeus...you see where I am going with this. I am not saying that aliens don't exist. According to basic probability,  it seems that aliens likely do exist. But that doesn't mean that they are responsible for every thing that hasn't been explained. Such claims are akin to a "God of the Gaps" argument and are entirely unscientific. The basic point, science requires evidence, and there is no evidence that aliens made crop circles. But fear not, as soon as there is evidence of aliens creating crop circles, scientists will relentlessly interrogate the evidence to either prove or disprove it.
