It means "unexpectedly" or "without warning." Originally it was "Out of the sky" or "Out of a clear blue sky." Asking who first said it is like asking who first said the word "tree."

It's an expressions, like "as a surprise". Something unexpected that came from nowhere. "Out of nowhere".
For example, if your uncle shows up uninvited, you can say she came out of the blue.
