A question for WM...

Wrt your logic, I have some questions:
____________
Are there infinitely many "dark" numbers?
Is there only a finite number of "light" numbers?
____________
As in a global database with all of the numbers witnessed by humans? Say a little kid, say 3 years old has never saw the number 42 before... So, this number is light because I just wrote it, it is not dark. However, it is "dark" wrt the the kid? If a number is stored in the database, is it light or dark, WM?
