Umm... how can we spell out an English phrase with geometric symbols?
Plus, if we're going on the hypothesis that there are aliens observing us, then we have to believe they have the science to come here from distant
stars, which would mean they'd have incredibly advanced technology (AI and quantum computers), so I'm pretty sure they have cataloged all of our
languages by now. It'd be a piece of cake to hack into and decode every single satellite orbiting us.
Why not just spell out "Welcome Alien Overlords" with some gasoline in a field? They'd understand it.
