The concept of "13 families descendants of Marduk". The 13 Families Specifically: Collier refers to 13 major families or bloodlines emerging from this interbreeding, categorized under the ancient term "Magi" (evoking mystery schools or priestly elites).

Alex Collier is a self-described contactee who claims to have communicated with extraterrestrial beings from the Andromeda constellation (often referred to as Andromedans). His lectures and writings, popular in ufology and conspiracy theory circles since the 1990s, blend ancient mythology, alien lore, and modern geopolitics. One recurring theme in his work involves the influence of ancient extraterrestrial races on Earth, including the Anunnaki from Nibiru (a hypothetical planet in some theories). The concept of "13 families descendants of Marduk" appears to stem from his discussions of hidden bloodlines controlling humanity, drawing from Sumerian/Babylonian myths where Marduk is a prominent god associated with creation, storms, and kingship—often portrayed as a son or descendant in Anunnaki lineages.Core Idea: The 13 Ruling Families as Hybrid DescendantsIn Collier's 1997 follow-up lecture and related materials, he describes how, over the last 5,000 years, Earth has been influenced by extraterrestrial groups from Sirius B and Nibiru (also spelled Nubiru or associated with Marduk in some interpretations). These groups include ancient figures like Enki, Enlil, and Marduk, whom he portrays as real extraterrestrial beings or "tribes" rather than mere mythological deities. According to Collier:

• Origin of the Families: The Nibiruans (Anunnaki) resulted from a genetic "marriage" or alliance between beings from Sirius B and Orion. They arrived on Earth and interbred with early humans, creating hybrid offspring or "half-breeds." These hybrids inherited advanced knowledge, technologies, and genetic traits from their extraterrestrial ancestors.
• The 13 Families Specifically: Collier refers to 13 major families or bloodlines emerging from this interbreeding, categorized under the ancient term "Magi" (evoking mystery schools or priestly elites). These families are said to carry a mix of Terran (Earth human) and extraterrestrial genetics from races that once "tyrannized" the planet. Marduk, as a key Anunnaki figure, is implicated in this lineage—his "descendants" symbolize branches of these bloodlines tied to control, power, and hidden rulership.
• Connection to Marduk: In Collier's framework (echoing broader Anunnaki theories from authors like Zecharia Sitchin), Marduk represents a faction of these ancient visitors. Nibiru is sometimes equated with Marduk's domain or influence, and its periodic orbit (every 12,000–24,000 years) allegedly disrupts Earth. The 13 families are portrayed as modern inheritors of this legacy, maintaining control through secrecy and manipulation. This ties into ideas of the Anunnaki experimenting on humanity (e.g., in Sumer or Africa) before departing, leaving their hybrid descendants behind.

Broader Implications in Collier's NarrativeCollier unpacks this as part of a larger cosmic drama:

• Control and Tyranny: These 13 families allegedly form the core of global elites (sometimes linked to the Illuminati or "Atlantean priesthood" descendants). They perpetuate cycles of oppression, using inherited technologies and knowledge to dominate economics, politics, and society. This echoes themes in works like Stewart Swerdlow's Blue Blood, True Blood, which references Collier and describes the 13 families as excluding certain royals (e.g., Japanese) while tying back to Anunnaki/Marduk origins.
• Extraterrestrial Agenda: The Andromedans (via Collier) warn that these bloodlines serve regressive alien interests, blocking human evolution toward higher consciousness. Marduk's descendants symbolize a "dark" faction opposing benevolent forces.
• Links to Other Theories: This idea overlaps with David Icke's reptilian bloodlines, the Illuminati's 13 families (e.g., Rothschilds, Rockefellers), and biblical Nephilim narratives. In galactic anthropology discussions, Collier's views on Nibiruans/Anunnaki (including Marduk) are analyzed as part of Enki/Enlil family rivalries, with humans as pawns.

Collier's claims are unsubstantiated and often critiqued as pseudoscience or fiction, but they resonate in alternative history communities. If you're referring to a specific lecture or source, more details could refine this unpacking.
