The WT publications used to teach that Adam, of all people, wrote a portion of Genesis and that Noah's family preserved copies of that portion of Genesis in the ark through the flood.
I've never heard that before - would love to see a quote. I'd guess it was something from the 20's or 30's.
David Splane claimed that the whole of archaeology, historiology and geology are all WRONG because their demonstrated age for the Great Sphinx contradicts the Governing Body's unsupported and egregiously dogmatic interpretation of Genesis.
The infuriating part of this is that he is one of the probably, at best, 2 or 3 guys on the GB with sufficient intelligence to actually understand how stupid his claim that it's "all wrong" is. So in the classic "evil or deluded" question regarding GB members, I think that puts him squarely on the "evil" side of the ledger.
