Jews forbid you to know about Merkabas. It's literally not to be taught except to the highest rabbis. Basically knowledge of rulling aliens spaceships. It's the prohibition that makes it more likely real.

The Talmudic interdictions concerning merkabah speculation are numerous and widely held. Discussions concerning the merkabah were limited to only the most worthy sages, and admonitory legends are preserved about the dangers of overzealous speculation concerning the merkabah.
For example, the secret doctrines might not be discussed in public: "Seek not out the things that are too hard for thee, neither search the things that are above thy strength. But what is commanded thee, think thereupon with reverence; for it is not needful for thee to see with thine eyes the things that are in secret."[12] It must be studied only by exemplary scholars: "Ma'aseh Bereshit must not be explained before two, nor Ma'aseh Merkabah before one, unless he be wise and understands it by himself."[13] Further commentary notes that the chapter-headings of Ma'aseh Merkabah may be taught, as was done by Rabbi Ḥiyya. According to Yer. Hagigah ii. 1, the teacher read the headings of the chapters, after which, subject to the approval of the teacher, the pupil read to the end of the chapter,[14] although Rabbi Zera said that even the chapter-headings might be communicated only to a person who was head of a school and was cautious in temperament.[15]
According to Rabbi Ammi, the secret doctrine might be entrusted only to one who possessed the five qualities enumerated in Isaiah 3:3 (being experienced in any of five different professions requiring good judgement), and a certain age is, of course, necessary. When R. Johanan wished to initiate R. Eliezer in the Ma'aseh Merkabah, the latter answered, "I am not yet old enough." A boy who recognized the meaning of חשמל (Ezekiel 1:4) was consumed by fire (Hagigah 13b), and the perils connected with the unauthorized discussion of these subjects are often described (Hagigah ii. 1; Shab. 80b).[15]"
Honestly there's very little way to interpret this other than they don't want you to know that space aliens rule or at least at one point did rule the Earth. We're talking about spaceships we're talking about vehicles that go up into the sky we're talking about the secret books of Jews and we're talking about a Prohibition about telling people about the spaceships that go up into the sky because people wouldn't be able to handle it.
I mean there's really no other way to interpret this.
If it was all nonsense there would not be a Prohibition about speculating about them.
