Open Challenge: Evidence of a Young Earth

The question of whether there is any scientific backing for creationism is of critical importance, in the US at least.I strongly suspect the real reason for YECism is religious. The number of YECs who are not religious literalists of one flavour or another is vanishingly small. However, a scientific backing is sought to try to give YECism validity as science. And why? Because a scientific model can be taught in school science lessons; a religious one can't.
