This afternoon, I watched an excellent scientific documentary on where Moses and the children of Israel crossed the Red Sea.  The evidence is that what is now called the Gulf of Aqaba was called the Red Sea in Moses' day.

There is much evidence that they crossed from the protruding, beach-looking area on the north side of the Gulf of Aqaba.  See below.  For example, on the bottom of the sea they have found evidence of coral-covered chariot wheels and other artifacts, evidence from the drowned Egyptian army, just as recorded in the Bible. It is amazing.

Many years ago, archaeologist Ron Wyatt came up with this, with videos, but as far as I know he is apparently being given any credit. See His Web site at http://www.wyattmuseum.com/red-sea-crossing-04.htm
