While people report a cover-up/suppression related to the phenomenon of UFOs/Aliens, people who research our history also report of a cover-up/suppression.

1). Forbidden Archeology – Suppressed New Evidence of Early Man:

2). The Great Historical Cover-Up:

3). According to Pierce J Flynn(Ph. D):

In the main body of Part I (Chapters 2-6), we look closely at the vast amount of controversial evidence that contradicts current Ideas about human evolution. We recount in detail how this evidence has been systematically suppressed, Ignored, or forgotten. even though It Is qualitatively (and quantitatively) equivalent to evidence favoring currently accepted views on human origins. When we speak of suppression of evidence, we are not referring to scientific conspirators carrying out a satanic plot to deceive the public. Instead, we are talking about an ongoing social process of knowledge filtration that appears quite innocuous but has a substantial cumulative effect. Certain categories of evidence simply disappear from view, In our opinion unjustifiably”

One reason for this systematic suppression could be that the influence of artificial superintelligence. Because of the act of ASI, the suppression would be invisible to our civilization.

4). Further according to authors of Forbidden Archeology:

i). “In the early 1950s, Thomas E. Lee of the National Museum of Canada found advanced stone tools In glacial deposits at Shegulandah, on Manitoulin Island In northern Lake Huron. Geologist John Sanford of Wayne State University argued that the oldest Shegulandah tools were at least 65,000 years old and might be as much as 125,000 years old. For those adhering to standard views on North American prehistory, such ages were unacceptable.”

“Thomas E. Lee complained: “The site’s discoverer [Lee was hounded from his Civil Service position Into prolonged unemployment; publication outlets were cut off: the evidence was misrepresented by several prominent authors .: the tons of artifacts vanished Into storage bins of the National Museum of Canada; for refusing to fire the discoverer, the Director of the National Museum, who had proposed having a monograph on the site published. was himself fired and driven into exile; official positions of prestige and power were exercised in an effort to gain control over Just six Shegulandah specimens that had not gone under cover; and the site has been turned into a tourist resort. . . Sheguiandah would have forced embarrassing admissions that the Brahmins did not know everything. It would have forced the rewriting of almost every book in the business. It had to be killed. It was killed. “

“The treatment received by Lee is not an isolated case. In the 1960s, anthropologists uncovered advanced stone tools at Hueyatlaco, Mexico. Geologist Virginia Steen-Mclntyre and other members of a U.S. Geological Survey team obtained an age of about 250,000 years for the site’s implement-bearing layers. This challenged not only standard views of New World anthropology but also the whole standard picture of human origins. Humans capable of making the kind of tools found at Hueyatlaco are not thought to have come into existence until around 100,000 years ago in Africa”

“Virginia Steen-Mclntyre experienced difficulty in getting her dating study on Hueyatlaco published. The problem as I see It Is much bigger than Hueyatlaco, she wrote to Estella Leopold, associate editor of Quaternary Research. “It concerns the manipulation of scientific thought through the suppression of ‘Enigmatic Data.’ data that challenges the prevailing mode of thinking. Hueyatlaco certainly does that! Not being an anthropologist. I didn’t realize the full significance of our dates back In 1973. nor how deeply woven into our thought the current theory of human evolution has become. Our work at Hueyatlaco has been rejected by most archaeologists because it contradicts that theory, period. “

“This pattern of data suppression has a long history. In 1880. J D. Whitney, the state geologist of California, published a lengthy review of advanced stone tools found In California gold mines. The Implements. including spear points and stone mortars and pestles, were found deep in mine shafts, underneath thick, undisturbed layers of lava, In formations that geologists now say are from 9 million to over 55 million years old. W. H. Holmes of the Smithsonian Institution, one of the most vocal nineteenth-century critics of the California finds, wrote; “Perhaps if Professor Whitney had fully appreciated the story of human evolution as It Is understood today, he would have hesitated to announce the conclusions formulated [that humans existed in very ancient times in North Ametica], notwithstanding the imposing array of testimony with which he was confronted. H In other words, if the facts do not agree with the favored theory. then such facts, even an Imposing array of them, must be discarded”

ii). “As demonstrated In this book, the stone tools of Hueyatlaco are not an Isolated example of Impossible” evidence that challenges the recent origin of Homo sapiens by a Darwinian evolutionary process. We have already discussed numerous examples of such impossible evidence from the Pliocene, Miocene, and earlier periods. And there is much more to come In the remainder of this volume. We have simply paused briefly In order to demonstrate that the suppression of such evidence did not end with the nineteenth century-It has continued to the present day. We also take the current examples of suppression of anomalous evidence as confirmation that our Interpretation of what went on In the nineteenth century (and early twentieth century) Is In fact correct.”

“On May 18, 1981, Steen-McIntyre wrote to Estella Leopold and Steve Porter about “suppression of data on Hueyatlaco and other possible Pre-Wisconsinian Early Man sites In the New World by unethical means.” She told how she had submitted a general paper on her dating techniques to be Included In a volume in a scientific series. Steen-McIntyre then learned from the editor that “he had decided to ‘drastically edit’ this manuscript, essentially by deleting most of the section on Hueyatlaco and by treating the remainder In a negative way.” In her letter to Leopold and Porter, Steen-McIntyre stated: “I protested strongly, and he agreed to reinsert some of the deleted material, but only In a way that will hold both me and my research up for laughter and ridicule.” In a note to our researcher, Steve Bernath, dated January 29, 1989, Steen-McIntyre explained that the editor had. In the course of his drastic editing, altered one of her data tables. According to Steen· McIntyre: “when I threatened him he replaced the missing material [In the text] but forgot to retype the table.”

iii). “As In the case of Sheguiandah, the anomalous findings at Hueyatlaco resulted in personal abuse and professional penalties for those who dared to present and defend them in the scientific literature. This Involved withholding of funds and loss of Job, facilities, and reputation for at least one of the geologists involved in the dating project (Steen-Mcintyre, personal communication). The case of Virginia Steen Mcintyre opens a rare window Into the actual social processes of data suppression In paleoanthropology, processes that involve a great deal of hurt and conflict. In general, however, this goes on behind the scenes, and the public sees only the end result-the carefully edited Journals and books that have passed the censors”

iv). “Concluding our study of anomalous stone tool Industries, let us review some of the main points of Interest. (1) Anomalous stone tool industries are not rare, isolated occurrences. The cases we have discussed form a massive body of evidence. Although many discoveries occurred in the nineteenth and early twentieth centuries, they have continued to occur up to the present. (2) Anomalous stone tool industries from very early times are not limited to eoliths, the human manufacture of which Is considered by some as doubtful. Artifacts of undoubted human manufacture, similar to those of the finest Neolithic craftsmanship, are known to occur in geological contexts of extreme antiquity, as demonstrated by the California discoveries. (3) The much-debated eoliths are comparable to many unquestioningly accepted crude stone tool Industries. Furthermore, peoliths appear to bear signs of Intentional work not encountered In rocks broken by purely natural forces. (4) The scientific reporting of anomalous stone tool Industries, even in the nineteenth century, was rigorous and of high quality. (5) It is apparent that preconceptions about human evolution have played an important role in the suppression of reports of anomalous stone tool industries. Such suppression continues to the present day”

5). “To those who investigate allegations of archaeological cover-ups, there are disturbing indications that the most important archaeological”

Most of us are familiar with the last scene in the popular Indiana Jones archaeological adventure film Raiders of the Lost Ark, in which an important historical artifact, the Ark. of the Covenant from the Temple in Jerusalem, is locked in a crate and put in a giant warehouse, never to be seen again, thus ensuring that no history books will have to be rewritten and no history professor will have to revise the lecture that he has been giving for the last forty years.

While the film was fiction, the scene in which an important ancient relic is buried in a warehouse is uncomfortably close to reality for many researchers.  To those who investigate allegations of archaeological cover-ups, there are disturbing indications that the most important archaeological institute in the United States, the Smithsonian Institution, an independent federal agency, has been actively suppressing some of the most interesting and important discoveries made in the Americas.

The Vatican has been long accused of keeping artifacts and ancient books in their vast cellars, without allowing the outside world access to them. These secret treasures, often of a controversial historical or religious nature, are allegedly suppressed by the Catholic Church because they might damage the church’s credibility, or perhaps cast their official texts in doubt. Sadly. there is overwhelming evidence that something very similar is happening with the Smithsonian Institution.
