What is the difference between expanding and creating?

a: creating applies only to ideas
b: expanding applies to something that already exists

Both expanding and creating involve bringing something new into existence, but there is a key difference in their focus. Creating typically involves generating something entirely new or original, such as ideas, concepts, or designs. On the other hand, expanding typically involves building upon or enhancing something that already exists, such as a business, product, or project. So, creating is more about the initial act of bringing something into existence, while expanding is more about growing or developing something that already exists.
