Mystery discovery: 'Alien coffins' found near ancient pyramids

"The precision is very 21st century, or at least 20th century"

The 25 granite boxes were found just 12 miles south from the Great Pyramid of Giza in the ancient necropolis of Saqqara near Memphis in Lower Egypt.

UFO hunters believe the high precision of engineering of each of the black stone boxes is remarkable, even by 21st century standards.

UFO and alien theorist Brien Foerster said: "The precision is very 21st century, or at least 20th century."

ALIEN: The black stone boxes feature extremely high precision engineering

He argues that the precision of construction of the surfaces of stone boxes, which are 100-tonnes with 30-tonne lids, and the angles are "within a few ten thousandths of an inch".

It is not known how the ancient Egyptians had the technology to make the skilfully cut stone boxes - leading UFO researchers to suggest they were designed and constructed by aliens that visited the country.

But some say that it should not surprise anyone that the ancient Egyptian engineers were capable of such remarkable engineering feat.

SACRED: It is believed the boxes may have been built for sacred Apis bulls

This comes as a bizarre UFO-shaped rock was discovered - sparking fears of an ancient alien civilisation.

A UFO was spotted in the skies above Devon and "human-like creature" was seen on Mars.

The tomb, the Serapeum of Saqqara, is believed to have been built around 1300 BCE by Rameses II.

It is believed to be the burial place of the sacred Apis bulls - a religious cult.

The bulls were worshipped as the incarnation of the god Ptah and were believed to live forever as gods after death.

Attempting to explain the purpose of the boxes, some Egyptologists suggested that they were intended to hold the mummified remains of the sacred bulls.

But none of the boxes contained mummified remains of the sacred Apis bulls.

UFO believers insist they must have been constructed to hold the mummified remains of giant humanoid aliens who never used them, possibly because they left Earth before they died.
