Is there a program that allows Age of Empires 3 work on a MacBook

If "Age of Empires 3" is a Windows based application, then if your MacBook meets the requirements of it, I would sugges you install BootCamp and Windows XP SP2 onto your MacBook, this will enable you to install and use Windows applications on your MacBook. You simply need to boot your Mac into the Windows mode during start-up. Or you can get the Mac version of Age OF Empires (See links below).
