OSPF Backbone Area Clarification

Dear Experts,

I have a stupid doubt, but it's bothering me a bit as i cant get it right
in my head.

I know that a OSPF network has a Backbone Area. What i fail to understand
is, why does the backbone Area always have to be Area 0? Why cant it be any
number between < 0 - 4294967295 >?

With Regards
