Photo from 1960's shows "Alien space-craft"

A self claimed UFO expert, Scott Waring, claims that this is a photo of an alien space-craft taken during NASA's Project Mercury mission back in the 1960's. He claimed that space-craft is "observing the Mercury capsule" as it is an " historical moment in human history"

This is not the first, and won't be the last, time that NASA's space photo's have come under scrutiny by the general public and self-proclaimed UFO experts. The apollo missions and the Gemini program are two projects, off the top of my head, that i know photo's have come out with "suspicious looking craft" in them.

So what do you guys think? are we alone?
