Rights vs Privileges

What is the difference between a right and a privilege?  Is there a difference?  Or are they the same thing?

A right is defined in most legal dictionaries as an entitlement, which is far different than a privilege or a license which are granted from a legal authority such a law or statute made by a state legislature, or the the Congress.
Rights, by definition, cannot require a license.

So, who gives us our rights?  Do they come from government, or from our creator?  Does our Constitution GIVE us rights?  Or is the Constitution supposed to PROTECT our rights?
