Depends on who you ask. Some say as few as 6,000 years or so, but it could be much longer.
The bottom line, however, is that the alternate theory boils down to "I found a book over here, so it must be the result of an explosion in a print shop."
I was just curious where all Creationists agreed on 6,000 years or whether there were different sects who disagreed about dates.
