Can't you imagine them stowing away on an interstellar flight purely
so that they can make such circles on another planet?

Take that to its logical conclusion and we would have been visited
long before now. Probably repeated over time by several mischievous
teenagers stealing their dad's spaceship. Then crashing them on Earth
while trying to do two things at once.

Making crop circles quickly gets boring if you are rebellious and from
an advanced civilisation. i.e. One capable of interstellar flight. To
have reached that point surely assumes some advances in society and
culture beyond bored teenagers.

Crop circles are strictly a pastime for those with very limited
ambitions. Rather like being a troll on a vanishingly small science
forum. A total waste of a very limited lifespan and whatever talents
were thrown up by their damaged genes. The very idea is simply
ridiculous.
