Are there really no such traditions anywhere else in human history, or does the Rabbi simply not know because he hasn’t checked thoroughly enough?

I haven’t looked into it deeply. I’ve seen people who did check, and they claim there’s nothing equivalent.

Are there religions besides Judaism that claim a national revelation?

Yes. For example,

Some religious groups believe that a deity was revealed or spoke before a large group of people, or they have legends with a similar impact. In Deuteronomy it says that the Lord was revealed in the giving of the Ten Commandments to the Israelites at Mount Sinai. In Christianity, the Book of Acts describes the day of Pentecost, when a large group of Jesus’ followers experienced a mass revelation. The Lakota believe that Ptesáŋwiŋ spoke directly to the people in establishing the Lakota religious traditions. Some versions of an Aztec legend tell of Huitzilopochtli speaking directly to the Aztec people upon their arrival in Anahuac. Historically, some emperors, cult leaders, and other figures were granted divinity, and their words were treated as revelations themselves.

Revelation – Wikipedia

Judaism is not the only tradition that claims a public revelation. In today’s world, several

That’s an answer I found on Quora in English and translated.
Do you have any response to the other revelations mentioned there?

I won’t answer in Michi’s name, but I suggest you watch one of the latest episodes in the “Faith” series. On that topic Michi did a good job and explained the uniqueness and advantages of the event that the Jewish people speak about.

If I remember correctly, he mentioned close to ten parameters for examining it. You’re welcome to listen, decide whether to evaluate things by those parameters, and if so, use them to decide whether Judaism is really unique.

The question is whether there is any group that has a tradition, passed down from generation to generation, of a direct revelation to their ancestors, and not just some campfire legend with vague details.

Every people’s story is different and distinct from every other story in certain respects. Isn’t that begging the question? In the same way, one could find points where the stories of Christianity differ from every other story, just with different criteria. I assume that Christian, Muslim, Hindu, and other religious people also use that to prove the truth of their religion.

With God’s help, on the eve of the holy Sabbath, “you shall surely inquire after your brother’s welfare”

To Yishai — greetings,

Following the things you quoted, I set out on a journey to examine the beliefs of the Aztecs and the Indians. Maybe I’d find something more successful than our old Torah 🙂

It turns out that Huitzilopochtli was a man who, following his military victory, declared himself a god and imposed his new religion with force and cruelty. The stories of wonders about the distant land he came from could be verified only by a group of elders who claimed they had traveled there.

By contrast, the Torah of Moses was given in divine revelation before the eyes of hundreds of thousands of people. Even though his Torah placed upon them the burden of commandments, not an easy one, demanded of them constant confrontation with “the whole world and his wife,” and brought upon them persecutions and forced conversions more than once — they clung to it even in the hardest times. Not only did they not lose their way, they even partially bequeathed the belief in divine unity to all humanity.

And behold what a wonder: whereas Huitzilopochtli was no different from other kings who gloried in their power and raised themselves to the level of a god, Moses, although he performed unparalleled wonders, remained “more humble than any man.” And his Torah makes clear that he too was human, he too was punished for his sins, and he too tasted death. On the contrary: Moses’ greatness led to exacting judgment with him “to a hair’s breadth.”

Huitzilopochtli established a religion according to which the sun would not rise unless a person — a captive or a member of the lower classes — were sacrificed to it every day. The Indians toned down the cruelty a bit, making do with the “Sun Dance,” whose climax is cutting a piece of flesh from the believer as an offering to the “Great Spirit.” By contrast, the Torah of Moses demands that a person sacrifice his impulses, restrain his desires, and draw close to his Creator through a life of holiness, of “doing justice, loving kindness, and walking humbly with your God.”

It may be that the Indians’ belief in the “Great Spirit” present in every creature has something of an approach toward monotheism, but even so there is a slide here into “pantheism,” which blurs the boundary between Creator and created.

One thing I think I’ll adopt this coming week is the “Indian bread,” made from dough fried in oil and sprinkled with powdered sugar. Why, that is… a jelly doughnut…
