I analyze Walt Brown's determination of the date of the Flood within his hydroplate model using the orbits of two comets. Brown's result is an unwarranted extrapolation of data gleaned from the literature. The uncertainty in the data expressed by the authors of that data show that Brown's result is unjustified, and hence Brown's statistical analysis is meaningless. The results of this determination of the date of the Flood highly depend upon the assumed ephemerides of the two comets. There is a considerable uncertainty in those ephemerides when extrapolated so far into the past, so this method to establish the date of the Flood is not possible.
