The satellite image from Google Maps is of a strange triangle shape in the River Plate in the city of Buenos Aires, Argentina.
In a series of pictures you can see a strange object flying and casting its shadow in the water.
And conspiracists think the “UFO” could be more signs of alien life in South America.
One commented on a video of the pictures: “Oh it’s a spaceship for sure.”
Another added: “That is very odd.”
And a third said: “Ahh I wonder if it is still there.”
But not everyone was convinced of the image, taken by Google in 2008.
One viewer wrote: “That is a boat or something.”
Many American’s believed this photo to prove the existence of UFO

The discovery comes on UFO day, which has been observed every year on July 2 since the holiday’s inception by UFO hunter Haktan Akdogan in 2001.
The existence of UFOs and other extraterrestrial travellers is a fiercely debated topic among so-called “alien truthers” and scientists alike.
Daily Star Online previously revealed a former NASA scientist claimed aliens exist but governments have covered up extraterrestrial encounters.
Kevin Knuth, who is now a professor of physics at the University of Albany, believes there is “plenty of evidence” to support the existence of UFO’s in our universe.

Earlier this year, ufologists claimed Google Maps provided further proof of aliens.
Netizens shared images from the satellite service showing what they claimed is an “alien HQ”.
And last week, sky-gazers filmed what appears to be a flying saucer-like UFO above the famous Nazca Lines in Peru.
Outlandish conspiracy theories have claimed they were created by ancient aliens thousands of years ago.
