Alexander the Great built Alexandria with stone blocks from the ancient city Heliopolis up near Giza, those blocks floated down the Rosetta branch of the Nile then east to Alexandria, and perhaps (just perhaps) the closer Canopic branch was utilized which ‘though had lost much of its flow by 300 b.c., down to nothing now, so how long before did it flow such that the now submerged ancient cities near Alexandria called Menouthis and Hercleion were rivermouth cities on that once mighty branch of the Nile? And why did he not mention those cities?
The experts say those cities went under by earthquake or a series of earthquakes between 300 and 1000 a.d., but where is the record of that in christian or muslim annuls, and why then would Alexander have gone all the way to Heliopolis for building stones when those massive blocks on the seafloor five miles from shore would certainly have done the trick? The answer is that those cities were submerged by a century long sea level rise when the ice age ended actually beginning circa 1500 b.c. when the Exodus too occurred, make sense?
