I come in peace

The rigorously accurate truth is in here. You always did suspect, didn’t you? Sure you did. And so, after much consideration, the time has come for conclusive confession:
Yes, I am an alien ambassador from another galaxy far far away, and this is my spaceplace that brought me here a long long time ago.

In case you wonder, yeah, I built the pyramids too… and introduced sudoko…

Now take me to your leader!
