Permitted by the mouth of a demon,
flying camel? Item,
and wheat that descended in the clouds.

Those discussing it back then thought this was possible.
The foolish world around them was full of such old wives' tales…

With God's help, 18 Sivan 5782

To the one who wrote about the flying camel — greetings,

Regarding "a flying camel," Rashi explained in Makkot 5 that these are camels that run very fast. Likewise, Rashi explained in Menachot 69 that "wheat that came in the clouds" means wheat that was on a ship, and a powerful storm blew it into the air and carried it great distances. Fast racing camels and hurricane-force storms are natural things, though very rare. See Rabbi Yaron Ben-David's article "Rain of Wheat" (Daf Yomi Portal, Menachot 69) and Dr. Moshe Raanan's article "Flying Camel," Daf Yomi Portal, Makkot 5.

In his article "If I Saw a Camel Flying in the Air" (on the tractate Nedarim portal), Dr. Raanan distinguishes between a camel literally flying in the air, which is an obviously impossible phenomenon and therefore an oath about it is a vain oath, and a camel running at high speed, which is something that does exist, though we do not take it into account because of its rarity.

And regarding the question that blessings of enjoyment were instituted only in the days of the Men of the Great Assembly: we already find in the days of Samuel, "for he will bless the sacrifice, and afterward those invited will eat"; this shows that in the time of Samuel the Prophet they practiced reciting a blessing before the sacrifice. It would seem that this was the custom of the pious and the prophets, and the Men of the Great Assembly later established it as an obligation for everyone.

Regarding the manna, the Talmud says that Rav Nachman said Moses instituted for Israel the blessing "Who sustains all" when the manna came down for them, and that refers to the blessing after eating. The first to discuss the blessing before eating manna was Rabbi Menachem Azariah of Fano, who discussed what blessing would be recited over the manna that God will feed the righteous at the future feast of the Leviathan, and following him an extensive discussion developed among the later authorities. See the literature cited in Haval Nachalato 19:51, and in Asher LiYehuda on the portion of Beshalach. In any case, as I wrote above, it seems likely that pious and righteous people were careful from earliest times to bless and thank God even before eating, as we find in the case of Samuel.

Best regards, Nesa"f

The Men of the Great Assembly instituted a blessing before eating.
Even if not the blessing itself specifically, which straightforwardly they did,
still they at least instituted the wording.

Otherwise, what does the expression "instituted" even mean?
What did they institute?
They just took credit? That doesn't make sense.

If so, they established "Who brings forth bread from the earth," or "by whose word all came to be," or "various kinds of nourishment."
Before that, either they did not recite any blessing at all before food, probably, or according to the narrower view there was no fixed wording.
Just: thanks God for the food.

If so, even according to the narrower view, what does it mean to ask which blessing they recited before eating the manna?
They hadn't invented that yet!
It's about like discussing what kind of tank King David rode in during his conquests…
