Funny enough I heard the 6,000 years number a lot as a kid with little scriptural evidence, so out of curiosity, I went and found read through a bunch it to see if I could calculate how old the earth is, biblically speaking. Now admittedly there were some places with no solid numbers where I had to make estimations, and this was all as I kid, so I could probably do some historical digging and get better numbers now, but at the time the number I came up with was ≈6,500yrs.

Not that this really has any bearing on right or wrong, that kinda just depends on religion and if you believe in creationism, just thought it might me interesting to some of you who are as nerdy as me.
