Overview
A presentation circulating on Slideshare and in UFO disclosure circles claims to catalog 150 extraterrestrial races along with their alleged home worlds, activities, and supposed influence on human affairs. Titled “150 razas extraterrestres,” the material presents itself as the product of years of research and cites a range of figures associated with UFO lore and alternative histories, including Carol Rosin, Corrado Malanga, Federiko Bellini, Anton Parks, Alex Collier, Bod Deam, Credo Mutwa and, in one reference, astronaut Edgar Mitchell. The presentation frames itself as an effort to reveal what it describes as hidden knowledge about off-world civilizations.
Key Claims in the Presentation
The slide deck organizes its narrative around a broad taxonomy of alien groups, including “Greys” from Zeta Reticulum and Orion, reptilian entities, Draconians from Alpha Draconis, Sirian beings, and Anunnaki linked to Nibiru. It attributes a variety of alleged behaviors to these groups: abductions, genetic experimentation, mental programming, cloning, hybridization between humans and aliens, and covert influence over governments and institutions. In its opening sections, the presentation also claims some races manipulate political and financial elites, while others are involved in technology exchange or long-term control of human evolution.
The source material goes further by describing purported consequences for humanity, including trauma among abductees, implanted surveillance, abuse of human rights, historical amnesia, militarism, religious division, organized crime, and culture-wide fear. These assertions are presented as part of a wider worldview in which extraterrestrial activity is intertwined with earthly power structures. The slides also suggest that certain races are engaged in competition with one another over control of humanity’s development and social systems.
Sources, Influences and Disclosure Culture
What stands out in the presentation is not just the breadth of its claims, but the way it blends UFO testimony, conspiracy theory, esoteric tradition and disclosure-era rhetoric. The author says the material comes from “good sources” and years of investigation, while also insisting that readers judge for themselves. That combination is common in disclosure communities, where presentations often mix anecdotal reports, alleged insider accounts and references to controversial researchers or witnesses who are popular in fringe-UFO circles.
The inclusion of names such as Carol Rosin and Edgar Mitchell is notable because both have appeared in broader discussions about UFO secrecy and government disclosure, though neither is known to have validated a catalog of 150 alien species. Likewise, references to figures such as Corrado Malanga and Anton Parks reflect the presentation’s ties to a wider body of speculative literature that has long circulated online, especially in Spanish-language conspiracy and alien forums.
Broader Context and Caution
Material like this tends to attract attention because it offers a sweeping, structured explanation for a wide range of unexplained or feared phenomena. In that sense, it functions as both a taxonomy and a narrative: a way of organizing anxieties about missing information, secret programs and hidden power. But despite its detailed tone, the presentation does not provide independently verifiable evidence for its central claims, and none of the alleged species or activities are recognized by mainstream science or government confirmation.
For readers, the document is best understood as a piece of UFO/conspiracy culture, not as established fact. Its significance lies less in proving the existence of 150 extraterrestrial races than in showing how disclosure-era narratives continue to evolve online—drawing on familiar alien archetypes, geopolitical suspicion and the enduring public appetite for hidden truths.
