10 historical signs that suggest aliens exist

There are historical and celestial anomalies in human history that make us question what we thought we knew about how technology and the stars interacted in the past. The Giza Plateau's unmatched geodetic accuracy and the strange ‘out-of-place’ artefacts like the Antikythera Mechanism are just two examples of unexplained things from around the world. Mainstream academia often says that these kinds of accomplishments are due to lost human creativity, but the fact that these sites are so complicated logistically and mathematically lends credence to the paleocontact hypothesis.

The Star of Bethlehem (Celestial Event)

Modern astrophysicists, publishing in journals like Quarterly Journal of the Royal Astronomical Society, suggest the ‘Star’ is a rare triple conjunction of Jupiter and Saturn. Many scholars have speculated as to what this celestial body actually represents based on its moving vertically or hovering over a specific area of space.

The Sacsayhuamán Walls (Peru)

While these stones, located around Cusco, weigh over 200 tons each, they are exhibiting zero-tolerance joinery, so that a piece of paper cannot be inserted between them. Archaeological research studies will demonstrate that dry-stone masonry methods provide resistance to earthquake forces using sophisticated interlocking construction techniques that defy the methods used to produce them.

The Costa Rica Spheres

More than 300 ‘Diqui Spheres’ exist, with some of them weighing as much as 16 tons and exhibiting near-perfect spherical geometry. According to research published by UNESCO, these spheres were made from gabbro or granodiorite between 600 CE and the present. How they were made, however, is the question that eludes us. There is mathematical precision in the production of these objects that can not be replicated with the primitive iron tools available during that time period.

The Black Knight Satellite (Earth Orbit)

The ‘Black Knight’ has been described as ‘an unknown object in a non-geosynchronous, polar orbit’ and was infamously captured on film during the NASA STS-88 mission. Although NASA has made an official statement indicating that the ‘Black Knight’ was officially identified as a jettisoned EVA thermal shroud lost during a space walk (EVA), there are proponents of ‘Paleocontact’ who have described Nikola Tesla receiving radio signals in 1899 as evidence of early, pre-20th-century contact with the mysterious satellite.

The Rendlesham Forest Incident (UK)

In 1980, when the event occurred, it was labelled Britain’s Roswell. At that point, there were many US Air Force members at the site who had all independently observed a metallic object that emitted light. Based on the release of government documents by the Ministry of Defence under the Freedom of Information Act, there were significant levels of radiation found at the crash site, and anomalies were found when tracking the object on radar for three days.

The Roswell Incident (USA)

In 1947, there was a highly publicised aircraft crash. The United States Air Force published their ‘Roswell Report’, which determined that the wreckage was debris from a top-secret endeavour, called ‘Project Mogul,’ to collect information about Soviet nuclear weapon development. Despite the US Air Force’s findings, the initial press release issued by them had referred to the object as a ‘Flying Disc’ and provided the backbone of UFO research related to the American government’s systemic institutional opacity and possible connections to extraterrestrials.

The Ubaid Lizard Figurines (Iraq)

Archaeologists unearthed anthropomorphic artefacts of lizard-like figures (with elongated heads and slit eyes) within the ancient ruins of Al Ubaid, which date to 7000 years ago and represent another major departure within the spiritual/religious culture of Near Eastern countries. British Museum archaeologists involved with this excavation noted that these ophidian figurines were unlike any other evidence of a humanoid form of worship currently unearthed in that region.

The Dogon Tribe’s Sirius Knowledge (Mali)

The Dogon people of Mali had highly advanced knowledge of Sirius B (a white dwarf star), which cannot be seen with the naked eye (not even with modern telescopes), before 1975. Human Anthropologists have documented in multiple studies, including in archives of the Smithsonian Institute, that the Dogon people knew about the density and orbit of the star 50 years ago when there were no telescopes available.

The Antikythera Mechanism (Greece)

The Antikythera Mechanism has been recognised as the first mechanical computer; it was recovered from a Roman shipwreck and dates back to the 1st century BCE and is documented in recent publications, including Nature, that it was able to track celestial cycles and predict eclipses 1500 years before the use of gears in that technological way in the world.

The Pyramids of Giza (Egypt)

The Great Pyramid has been calculated to achieve geodetic alignment to an accuracy of three-sixtieths of a degree, as confirmed by many archaeologists, with the additional precision of math and the difficulty of transporting the 2.3 million blocks of stone used to construct it being further evidence of advanced geodetic knowledge that has yet to be matched by any other construction project.

Actually all this information were available inside the world biggest library in India at Nalanda University called as the first University on the world. The Uneducated and un civilised britishers burnt the library so Indians can never be educated, but with that they also destroyed the knowledge where people from all around the world use to come and get. All at the answers were gone and today we are reading this article in TOI and thinking wow how could that be possible?
