Avi,
Sefer Yetzirah as per the Talmud in Sanhedrin is basically totally Artificial.
The very same issue pertains to Chanukah – there is the famous question (it is repeated in the name of Rav Chaim of Brisk) about the Nes on Chanukah, according to the ones that the vesel refilled itself with new “miracle” oil – how can it be used for “Shemen Menorah” – after all it is not “shemen Zayis” , it is rather some artificial “miracle oil” which is not “Olive Oil”.
Some dispute the above from the Gemora in Menachos regarding Omer – wheat that came through a Nes, that the problem is not the “miracle” but rather, that it is not from Eretz Yisrael…
