The (lengthy) article on The Flood at your website
http://antspub.com, made some reasonable points up to where I stopped reading.
However, I don't think the 12 page(!!) diversion about God's alleged 'Rainbow Covenant', including the physics of rainbows, the physiology & genetics of vision, quantum mechanics, nuclear physics, stellar fusion, cosmology, black holes and quasars, Hawking radiation, dark matter, and more(!), was really necessary - the rainbow covenant isn't really relevant to the question of whether there was a flood (also, that biblical passage could simply be interpreted as God
adopting the rainbow as a symbol of the covenant).
Criticising the numerology in the story, and the improbability (impossibility) of the quoted dates and times, isn't that difficult - biblical dates and times are notoriously unreliable and often symbolic - e.g. repeated mentions of '7 days' and - '40 days and nights' were generally not supposed to be taken literally; '40 days and nights' meant 'a long time' - the number 40 (for some reason) had great symbolic meaning.
Whether there was a removable cover on the ark, and whether Noah should have opened a window to spot land, also seem somewhat incidental to the rebuttal...
I ran out of time and patience at that point.
