Uh huh. Sure. Of course you do. Here's a cookie.
Look, son, I'm sure you believe that, because the creationist propaganda factories produce that lie over and over again, and you made the mistake of believing it. But it's not true. And while there may be a few confused idiots in with "credentials" who have bought into the same lies, it quite simply is not true. Read any ACTUAL science journals in the field, and you'll quickly learn the scores of different ways in which dating is performed in NONcircular ways. No amount of foot-stomping and declaring "is so, is so!" by creationist liars will make that fact disappear. So stop following the people who are lying to you, and learn to think for yourself for a change, start to learn the field yourself instead of relying on the falsehoods of others. In short, stop acting like an empty-headed Michael Moore groupie who swallows any crap he's fed, and rejects any and all evidence to the contrary out of hand because he "knows" that his hero is right...
The creationists have lied to you. A lot. It's not hard for you to look around at actual science journals and discover that they contain material that the creationists have dishonestly claimed doesn't exist. All you need do is look, and be honest with yourself. If not, well -- complete this sentence: "There are none so blind..."
Science is guesswork, at best, when it comes to trying to prove evolution. Why is it guesswork...because they just keep floating new theories hoping that one will stick in the minds of men. Guesswork of men? Word of God? No Brainer.
