If aliens visit us, I can only imagine three scenarios: invasion, first contact, duck blind observation. The crop circles would fit into the latter category
As our current knowledge about astrophysics suggests that M class planets are rare and interstellar travel virtually impossible, these aliens would have a far superior technology. One that should allow them to conduct a duck blind mission without leaving behind traces that we could detect.
