I'm not saying it's aliens, but it's definitely aliens. I mean, if the aliens are hiding the first places we should look are deep in the ocean and on the dark side of the moon.
Just imagine how bizarre, unexpected and awesome it would be if in two months there was a press conference with Xi Jinping announcing to the world that they found a cube/monolith with strange inscriptions on the moon...
Kind of horrifying, actually. Imagine some intelligent life discovered Earth and its primates and dropped us a calling card in a place we will only find when we're sufficiently advanced.
