2.Walt Brown Ph.D
Real PhD, mechanical engineering, MIT, no less.
Real, really, seriously crackpot ideas and online book at Center for Scientific Creation – In the Beginning: Compelling Evidence for Creation and the Flood
I can spend hours finding and shooting down the absurdities, misrepresentations of real scientific papers, and just plain ol' stupidity on that website. The guy reads like a satire, but, sadly, he is apparently sincere. Delusional, but sincere.

ALL traces of DNA will disappear under adverse conditions or within
8 THOUSAND years (whatever comes 1st).
Nope.
Genetic analyses of permafrost and temperate sediments reveal that plant and animal DNA may be preserved for long periods, even in the absence of obvious macrofossils. In Siberia, five permafrost cores ranging from 400,000 to 10,000 years old contained at least 19 different plant taxa, including the oldest authenticated ancient DNA sequences known, and megafaunal sequences including mammoth, bison, and horse. The genetic data record a number of dramatic changes in the taxonomic diversity and composition of Beringian vegetation and fauna. Temperate cave sediments in New Zealand also yielded DNA sequences of extinct biota, including two species of ratite moa, and 29 plant taxa characteristic of the prehuman environment. Therefore, many sedimentary deposits may contain unique, and widespread, genetic records of paleoenvironments.
