All But One

In this photograph is every single human, alive or dead, except one!

That is correct. At the moment this photo was taken, all humans, living or dead, are contained in the frame of this photograph, except one. Think about it for a second. The spacecraft is the lunar landing module and contains the two astronauts who landed on the moon, Neil Armstrong and Buzz Aldrin. Earth, in the background, contains every person living and dead that existed up to that moment. The only person missing is the only other person not on the planet Earth and not in the spacecraft, that being Michael Collins, who remained on Apollo 11 and took the photo.
