Citing the parting of the Red Sea in an argument about the existing of a god - especially that of a god as described in the Hebrew, Christian and Muslim texts is highly problematic.

There is no archaeological evidence Jews were in Egypt during the historical period described in Genesis. In fact archaeological evidence strongly suggest the Jewish kingdoms and faith coalescing in the Levant following the collapse of the Hittite Empire and the parallel retraction of Egypt from the area responding to what may have been the invasion of the ‘Sea People’ whoever they were, or, just as likely, general unrest, weather and other environmental pressures.

Nor were the Jews as unique as biblical historians often argue. In fact their approach to faith, along with many of the legends recorded in the Bible have close counterparts among the faiths of other cultural and political societies that formed in the region but were just not as lucky over time as the Jews.
