After reading this and many other threads, it seems painfully obvious that YECs KNOW they can never prove a young Earth. Why? Because, as Percy pointed out in his post above, there are no mammals in the Cambrian. If Creationists really did believe they could prove a young Earth and disprove evolution, they would all be out in the field digging through every Cambrian/Precambrian outcrop looking for those pesky mammals, or the Jurassic looking for humans. Instead, they waste their time trying to prove CPT when much easier ways exist to prove their theory.
At this point, there is absolutely no reason at all to support CPT. As Rockhound stated, Dr. Baumgardner did not develop CPT as an alternative to PT. There was no need since PT explains the available physical evidence extrememly well. Baumgardner's entire motivation for developing CPT was to support the Bible ONLY. He has absolutely no supporting evidence whatsoever!! Nor is he, or anyone, ever likely to find any.
TC, if you really want to prove YEC, go out to the field and find a human (or a fish or dinosaur or mammal or flower etc. etc. etc.) in the Cambrian. That's all! It's very simple.
And if Creationist organizations were serious about proving once and for all that Creation is true, they would ALL be out there conducting those types of studies or paying others to do it. As complex as the geologic record and evolutionary theory are, they would come tumbling down quickly and easily with just a few anomalous fossil finds.
