You can call it "God", meaning the above is your definition of "God". But I think that is highly misleading because the word "God" is used in the Bible and it speaks about a very specific type of thing, not defined like you define it but as something which created everything in 7 days, spoke to Moses etc. Using the same term "God" as Bible, Book of Mormon, Koran and other books do but with a different "definition" is highly confusing and misleading. You should call the "cause of existence" simply "Cause of Existence". If you need a shorter way to refer to it a good one would be "CoE", not "God". Why use the same name as Bible unless you are saying you are talking about the same thing that Bible is, the thing that spoke to Moses?
