Hold on to your skeptical horses, Ralph, and enjoy your Seder meal, being aware that modern scholarship (Oxford University Press, no less) is historically and archaeologically confirming what you dismiss as man-made myth.

“Israel in Egypt: The Evidence for the Authenticity of the Exodus Tradition” (2011) by James K. Hoffmeier.

Abstract:

“Scholars of the Hebrew Bible have in the last decade begun to question the historical accuracy of the Israelite sojourn in Egypt, as described in the book of Exodus. The reason for the rejection of the exodus tradition is said to be the lack of historical and archaeological evidence in Egypt. Those advancing these claims, however, are not specialists in the study of Egyptian history, culture, and archaeology. This book examines the most current Egyptological evidence and argues that it supports the biblical record concerning Israel in Egypt.”
