Glenn: Your link includes the following:

*To completely erode flood sediments takes more than 20,000 years.

There are no widespread sediments dating from less than 20,000 years ago. *
*
*Even accepting the general accuracy of these statements, this leaves the
possibility of older sediments that have been completely or partially
eroded. I can't find it now, but in some post of yours to this list from a
few years ago that I stumbled across you gave an earlier time frame for the
erosion of flood sediments.

The comparison to a couple of glacial dam floods seems wrong to me.
Honestly, it seems like a bit of slieght of hand. I'm no geologist, but I'm
not so naive to think that a glacial dam flood in the Rocky Mountains would
leave the same geological traces as even a huge river flood in the
Mesopotamian basin.

The passing down of the story thing is no big deal IMHO, if the Bible is
inspired by God. Maybe the story was passed down, maybe it was a story
dimly remembered and recovered by the inspiration of the Holy Spirit.

I found that article in about 30 minutes of Google searching, having no clue
whatsoever to look for. A bit more Googling tonight turned up numerous
articles about the marshlands of southern Iraq, the Holocene marine deposits
showing that the Gulf has receded, etc. In short, it appears to me that the
data you're citing in support of your theory is extremely selective.
Whether or not Noah's flood was as long ago as you say, or was a big
but ordinary river flood a few thousand years ago, or was a bigger river
flood longer ago, or was something else even longer ago, or was in the North
of Iraq, or the South, or somewhere else, I don't know. I know there's
strong textural evidence in the Bible and in the Gilgamesh epic for a highly
significant flood event somewhere in Mesopotamia, and that there are
reasonable textural questions about where the ark landed, and that's about
it. I don't want this to sound snippy or something, but I don't fully trust
what you're saying when you seemingly ignore lots of relevant stuff and make
inapposite comparisons to rocky mountain glacier dam floods. For now I'll
reserve judgment and I guess if this continues to interest me I'll study it
some more.
