In a recent article in Terra Nova, Kristan-Tollmann and Tollmann (1994
) suggested that the Biblical Flood can be explained by seven fragment
s of a comet that impacted the ocean at seven locations on Earth at 03
.00h (C.E.T.) on 23 September, 9545 yr sp. We demonstrate that all the
'geological proofs' that allegedly support their conclusions are not
supported by the available data on impact cratering. Their hypothesis
is based on insufficient and ambiguous data, selective citation, and i
ncomplete comprehension of previous research.
