The existence of soft tissues and proteins within bones of anything considered older than 50,000 years isn't convenient to the "established" viewpoint. It is amazing for that very reason!
You do realize how long a span 70 million years covers? Recorded earth history doesn't even go back an iota's measure of that span... 70,000,000 years (25,578,000,000 days

)... You're claiming to tell me that the effects of entropy on a system far removed from absolute zero temperatures can be glossed over simply by stating that [science] is
"changing the theories of decay"... You do realize that this is why fossilization occurs in the first place, right? Because most organic bonds are covalent and can't overcome extended periods of time without complete degradation... that's why our own proteins and genetic compounds are constantly being replenished by our bodies, that's why our cells have limited life-spans... that's why even the highly stable cellulose polymers in most plants will petrify over time... That's why much of the degradative products from dead biomass was converted into petroleum over the course of the years (in the bowels of the earth)...
Who's being deceived here??
But hey... we'll wait to see what creative scheme your athiest buddies can come up with to keep that wool's cloth over your eyes... I'm sure you'll accept anything.
This is as big as the "Dead Sea Scrolls" was to addressing the naysayers accusations about the alleged fidelity loss that was accrued from years and years of biblical text propagation. The Dead Sea Scrolls (from 200 B.C.) read almost identically to texts written in 1000 A.D. (the oldest scripts from the Hebrew Canon in existence at the time the Dead Sea Scrolls were discovered).
You just haven't realized how big this discovery is yet...
