Such as jews being mentioned in Egyptian texts, or other sources placing them in Egypt, or perhaps evidence of jewish burials? Any mention outside of the bible of the jews leaving Egypt (with or withouth the nile turning into blood and locusts...).
If not, are there any theories about the factual basis of the enslavment in Egypt or is it just a story?
It is worth noting that archaeology should not be used to comment on discrete historical events. The only sort of archaeological evidence that could have a bearing on the Exodus would be an inscription.
hi! not discouraging anyone from making a direct response, but FYI, you'll find several posts on both topics in the FAQ (link on sidebar)
