Like God creating the heavens and the earth by means of 22 Hebrew letters, for instance. "By the word of the Lord were the heavens made," "For he spake, and it was done," Psalms 33:6, 9, the "word of the Lord," and "he spake," in this passage Kabbalist Judaism interprets to mean God uttering the 22 Hebrew letters.
Maybe the Kabbalists on this thread will care to tell us which Hebrew letter God spoke to create the land, which one the seas, the vegetation, etc.
Such a great question! You’re right—it is exactly a kabbalist’s job description.
I’ll answer (though not a kabbalist myself) with an example of Man. Man in Hebrew is adam. In our Yeshaya, 14:14, we find (in Hebrew) ADAM-EH L’ELYON, (I will be like the Most High)
ADAM-EH means “to be similar (to)” This is the basis of the etymology of Man being “in the image” of G-d. He created our existing spiritual and physical worlds with the Holy Tonge (Hebrew) and the Torah can only be understood, in plain meaning and in contextual meaning, with an understanding of Hebrew.
...if you remain unconvinced, I won’t be offended.
For graduate Jewish study, here is a chapter of Rabbi Shneur Zalman of Liadi, ZT’L, the innovater of the Lubavitch chassidic movement’s “Shar haYichud v’Emunah” (The Gates of Unity and Faith” talking about your question:

It’s hard to convey the meaning in a linked interlinear (with one language being illegible to the other party) website. If you really want to understand more PM me please.
IN BRIEF ANSWER TO YOUR LAST QUESTION-— (which Hebrew letter...) it was actually the words, the combination of the letters (each with its own energy) that counts.
