I have something akin to a video of you, with your face clear, holding a gun and shooting someone in the back of their head, witnesses corroborating the story, your manifesto, DNA tested + stylometry analysis, claiming that you were going to do that, your fingerprints on the gun (your gun), gunpowder & the victim's blood on your clothes and hands, and you, confessing it straight to my face 20 minutes before, and the whole police department.
But yeah, besides from that, not much else. Also, the sun is actually a unicorn and you have no proof of this being otherwise.
Do you even know if I exist? Pyramids were made by beavers actually. India doesn't exist, and Abraham Lincoln was, in fact, from the Berber ethnic group.
