Conspiracy Theorist Gauntlet

From the introduction: You enter a world much like ours. Indeed to the everyday member of the public it would be indistinguishable. However, in this world at least one major conspiracy theory from our world is true and perhaps more depending on your choices. Your mission is to prove to the general public the truth of the conspiracy theories you choose below. This follows the standard rules of a gauntlet. You may choose any age and gender, you may choose to be a drop in or have lived an average life in this world.
