Pranksters, artists or aliens aka another monolith.

this has to be some sort of art project. Like when they're all out there, if you connect the dots it'll form like, dickbutt or something

My hunch is still bored artists!

Oh man, this next one's close to where my childhood best penfriend grew up. (Doubt she still lives there, but you never know)

But yeah, sounds like artists in lockdown deciding to have some crazy fun

I love it

There's someone on Youtube claiming responsibility.

Why did I build Monoliths all around the World?

No idea why it showed up on my youtube feed, but there it is.

Still thinking bored artists myself
