I am soooooo glad that all those Aliens out there constructed all those Giant faces on the Moon and Planets for us to see so we know that they really exist
They don't have the technology to build radios so they constructed Giant Indian Heads, the worlds famous "woman's figure," a worm animal, military tank, as signs of "Hey look, here we are!"
But I am really extra proud of them for their ability to make their massive camouflaged buildings look remarkably like rocks. Amazing!
