"Ervin is talking about the how conventional scientific evidence shows that dinosaurs existed before humankind."

Correction:  "conventional" science claims that dinosaurs existed before man, and they are correct, but only in part.  Land animals were created a few minutes or a few hours before man, since man was the crowning act of Creation, but not "millions of years" before man.  That cannot be proven because the methods used to determine the age of dinosaurs rely too much on assumptions which cannot be proven.  This has been adequately explained by many creationist scientists.  Furthermore, when God finished the creation process, He said everything was "very good."  Death is not "very good."  No death before sin.  Clear as can be.

Either we accept the Genesis record or not.  If not, the rest of the Bible becomes suspect and we might just as well toss out the Resurrection, because that's just as unscientific as creation ex nihilo.
