Yep, hoax. The closest we've come to identification of sites mentioned in Exodus is that of Pi-Ramese (Tel Quantir) Biblical 'Ramses'. That was a stonking great new capital city built by Ramesses II in the Delta....but when that branch of the Nile silted up three or four centuries later, all the stone structures were moved in a fantastic effort, to the 'new' city capital, Djanet (Tanis) What remained was found in the last two decades. Unfortunately, with the rise and fall of the Nile in that area, any remnants of mud brick structures are lost completely, so we can't study them.
