Aliens, Angels, and Demons: Extraterrestrial Life in Judaism and Kabbalah and Its Vital Relevance for Modern Times
By Rabbi Ariel B. Tzadok
Ancient Torah and biblical stories describe beings descending from the skies or other realms. Were they angels or demons, as religious traditions claim, or extraterrestrials, as scientists might interpret them? Could they actually be the same?
The Bible often blurs these lines. Accounts of angelic visitations could easily describe UFOs or alien encounters. The Torah appears to affirm extraterrestrial life—“from outside this world”—and angels and demons clearly fit that category. Rabbinic and Kabbalistic sources speculate that life exists on other planets, though with less free will than humans, and some suggest aliens have visited Earth in the past.
Kabbalah teaches that God created and destroyed several worlds before ours. We live in the final of seven cosmic cycles, the stage where humanity must “get it right.” Remnants of those earlier worlds may survive—perhaps underground or in the skies.
The Bible offers symbolic hints of prior beings, such as the “ten kings of Edom.” Even the Tower of Babel raises questions. Why destroy it if heaven isn’t in outer space? Some interpretations suggest it was a technological project, possibly opposed by extraterrestrial entities, or an attempt to confront God after the Flood.
Angels serve as God’s messengers. Rabbinic tradition describes ten species, some semi-physical and able to eat and drink (as when visiting Abraham), others purely elemental. Each person and nation has a guardian angel. Wars on Earth often reflect heavenly battles between national angels, who guide humanity through challenges toward moral growth. To visit Earth, these beings may need temporary bodies, much like in the movie Avatar. Communication might occur through telepathy.
The author emphasizes that angels and demons are better understood as ultraterrestrials—beings from other dimensions who can enter our reality at will—rather than extraterrestrials from distant planets.
Demons, according to the book, were partially created during the first six days but left incomplete at the Sabbath. They envy humans and sometimes mate with them, producing hybrids. Some link demons to fallen “Watchers” who took physical form and fathered the giant Nephilim; when the giants died, their spirits became demons.
Rabbi Ariel Sadok’s book reveals that the Torah and Kabbalah not only allow for but directly address angels, demons, and extraterrestrial life. I was surprised and excited to discover how these ancient texts engage with such modern questions. It makes the existence of such beings highly plausible within a traditional Jewish framework.
This thought-provoking work bridges ancient mysticism with contemporary debates about life beyond Earth, offering fresh insights for anyone interested in faith, spirituality, and the unknown.
