It's not hoaxes, it's art. If they were hoaxes the makers would be trying to convince people they were "real", they're not, they just make their pretty pictures and go. That's called art (actually it's called graffiti, but most of that looks better than the crap people call art these days).

And be careful about trying to tie this into a crevo arguement. A lot of the UFOnauts think the aliens put life on this planet. You could find yourself calling God a little green man if you don't step lively.

Why do you assume I think aliens had to make teh circles?
