It's true. Though carbon dating, and similar processes, can be called into question, we can reasonably say that the Earth is at least a little older than 6,000 years. Erosion, ice cores, sedimentary rock, the list goes on.
The bottom line is that there is much more actual evidence in support of the earth being billions of years old, than the circumstantial evidence provided by creationism, and other religous bases. Not very much room for discussion...
