The current series by Mark Snoeberger about this subject made me think that this would be a great poll question.
I was influenced by Henry Morris, who suggested the earth was perhaps 10,000 years old. Since Ken Ham has become popular, the new creationist party line has returned to Bishop Ussher's chronology, setting the date for creation at 4004 B.C. This, of course, raises both historical and textual questions. How dependable are the numbers/ages in the genealogies? Are these merely highlight descendants, or a complete list? How do we account for the differing numbers (regarding age) between the LXX and the Masoretic text?
A lot to talk about here, is there not? We are talking about what we believe to be true, not what we know as a fact. This is about opinion and conclusions we may have drawn, even if loosely.
Orthodox Judaism puts our year as 5782, under 6 K a bit, FYI.
Run with the ball in any of these directions, if you wish. But here is a bit of advice: keep it brief, to the point, and be thrifty with links. You can, however, comment in more detail if you wish by discussing the first (and forthcoming) article by Mark Snoeberger. That would be a great place for debating and arguing on behalf of your viewpoint. This is more of a survey to see where SI participants stand on this issue.
