Some people just never get tired of trying to prove the Moon landing was a hoax.
This time, it's a video that was uploaded to YouTube and has gotten around a million views.
Newsweek reports the uploader, looking at an old photo from the Apollo 17 mission, claims to have spotted a person not wearing a spacesuit in the reflection of the helmet visor of an Astronaut walking on the moon.
But some commenters say it looks just like another astronaut to them.
And some point out that these days, just about anyone with simple software can convincingly alter a photo.
