Those have to be really stupid aliens.
Their highest level of technology is 6 people and a string, their most useful tools are their boots, and they aren't able to communicate except by stomping various grains during grain-growing season, those folks are pathetic.
One would expect at least they could learn English, or French. Or that they be able to communicate in a more straight-forward manner, in a way which conveyed information.
Even "God" used the Bible, a step up in a way but with the opposite problem. One can find anything one wants in it.
I have to admit to no respect for the crop circle aliens. Not particularly bright or accomplished, some other aliens must have dropped them off. Like the city folks dropping off a litter of kittens in the country.
