Season 18's fifth episode builds its case around a 2011 video showing a pulsating light descending onto Jerusalem's Temple Mount, which some Ancient Aliens theorists interpret as a technological activation of the Ark of the Covenant buried beneath the Dome of the Rock. The episode presents the Ark—a gold-covered acacia wood chest built to house the Ten Commandments and described in Exodus as roughly four feet long—as potentially far more than a religious container. Theorists cited in the episode argue that biblical descriptions of the Ark bringing down Jericho's walls, smiting enemies, and causing disease suggest it was an advanced technological device rather than a spiritual symbol, with its disappearance around 586 BCE launching centuries of speculation about whether it was hidden, looted, or moved to locations ranging from Ethiopia to beneath the Temple Mount itself.
Mainstream archaeology treats the Ark as a sacred container central to ancient Israelite religion, with its physical existence documented in biblical texts but its fate unknown after the Babylonian conquest of Jerusalem. Historians note that no contemporary archaeological evidence confirms the Ark's technological capabilities, and the 2011 Temple Mount video has been widely analyzed as either a hoax or misidentified conventional phenomena. The episode remains compelling because it grapples with a genuinely unsolved historical mystery—the Ark's disappearance is real, its location unknown—while exploring how ancient texts describing divine power might be reinterpreted through a technological lens, a question that resonates regardless of whether one accepts the extraterrestrial hypothesis.

Ethiopia · Aksumite
Ancient Aliens claims the Axum Obelisk and nearby ruins represent extraterrestrial influence on the Aksumite civilization, with the obelisk's precise engineering and astronomical alignment suggesting alien contact. The site's connection to Ark of the Covenant legends is presented as evidence of alien intervention.

Port of La Rochelle
France · Medieval
Theorists argue that the fleet of 18 Knights Templar ships docked at La Rochelle vanished before King Philip IV's forces could seize them on October 13, 1307, suggesting the Templars escaped with the Ark of the Covenant and other holy relics to Scotland. Historical records confirm the Templar fleet disappeared from La Rochelle but its ultimate destination remains unknown.

Theorists argue that the ngoma lungundu, a charred ancient wooden object discovered by Tudor Parfitt in a Harare museum storeroom, is the closest surviving remnant of the original Ark of the Covenant, reconstructed by the Lemba people from a piece of the destroyed original. Critics note that the crude object bears little resemblance to the biblical descriptions of the Ark, and mainstream scholars treat Parfitt's claim as speculative.
