Photos of alien walking on a garden in Guthrie City, Oklahoma surfaced online moments before it jet off in a UFO. The alien appears in a boxy-form, which looks like it is trailing a limb.

The images were captured by a motion-triggered camera. The owner noticed them only when the pictures were about to be deleted. There seems to be a mysterious shape which appear and then disappear in their garden.

The mystery was even intensified when several hours after those images were discovered, another mysterious shape appears in the sky, which disappears in some photos that were taken every minute in the same place.

According to Dailystar.co.uk, the owner of the camera decided to endorse the pictures to UFO sightings network MUFON while adding that those photos were captured just this month.

The owners of the house was deleting pictures when this human form caught their eye less than 200ft from their house.

"We have nothing that would look like this thing out the back," the said.

With the other object that appeared in the sky, they further shared, "It's too big to be a bird and not the shape of anything I have ever seen in the sky. This one was taken about seven hours after."

The witnesses likened this alien to a human boxy-form, packed with what looks like several ribs and trailing a thing, which the witnesses also identified as a limb.

Because of this, it has been rumored that the box was like a space suit used by aliens that are capable of enduring the climate here on Earth.
