Why do people say Hashem wrote the torah, shouldn't it be He created it, made it, edited it, etc?
Hashem is the author of the Torah. Generally the author of a work writes it. Actually nowadays the author generally types it, nevertheless, we still say so and so "wrote" it. Who transcribed it or how they did so is incidental to who authored it.
In other words saying Hashem wrote the Torah is just a generic way to convey in English that Hashem is its author.
Well he dictated it to Moshe who wrote it,But it already existed in Shamayim as we know based on the story of Moshe going up to get it it by Kabbolos Hatorah and we also know that it was the blueprint for the world as we know Hashem looked into the torah and created the world.The closest thing I can think of where Hashem sort of wrote was the question is asked if Moshe died on Shabbos how did he write the 12 sefer torahs for the Shevatim one answer is given is He use An Incantaion and they got written I guess you can call that Hashem wrote it.
