Thomas has written well and often on the subject of what scientific evidence shows and does not show about dino tissue preservation but he too makes hos own leaps of logic and interpretation. That dino tissue might under very rare circumstances be preserved for thousands of years it does not follow that the earth can thus be only thousands of years old or show that the earth could not have existed without life for some long period of time.
Proving the evolutionists are in error does not prove the young earth creationists correct.
Barry Setterfield has done the heavy cosmological work of showing that the Earth has to be approximately 6000 years old based on the expansion of the universe and the observed ‘quantized’ red shifts.
