Is the Exodus from Egypt Factual?

The Exodus from Egypt is one of the most important stories in the entire Tanakh. It tells the story of how the Israelites were slaves in Egypt for 400 years and how Moses led them out. Although there are no reliable records that allow us to ensure that we were really enslaved in Egypt, I believe that we were. The Tanakh wouldn't go through twelve chapters of constantly explaining how miserable we were and how much we suffered to tell us that it was just a story. Although there is no factual evidence, there are theories that are backed with evidence about many of the other teachings of the Tanakh. If some of it is proved to be true then it is very likely that the rest of it is as well.
