I agree. However, if someone wants to argue for or against a view, they should try to present their evidence correctly. I fail at this, but I try. The 6,000+ year date tends to come from Ussher (http://en.wikipedia.org/wiki/James_Ussher) who tried to come up with the age of the world based on the Bible. However, organizations like ICR (Institute for Creation Research) and Answers in Genesis use dates that are older than 6,000+ years. I have seen dates ranging from 10,000 - 20,000 years, though others might be used.

To make matters even more confusing, some creationists are "old earth" creationists. As such, they might hold to millions or billions of years.

It might be better, in a discussion on Creationism/Intelligent Design and Evolution, to use terms like "thousands of years" as compared to "billions of years".
