The short answer: no, no, and no.

The longer answer: you can get a lot of helpful information from /r/AcademicBiblical (I was asking about Exodus recently myself). There is no evidence of a mass Israelite exodus from Egypt/mass enslavement in Egypt. It's theorized that the story came about to explain how they entered The Promised Land

Some scientists have said it could, theoretically, be possible for a strong wind to appear to split the sea, but this is strictly theoretical.

It is also theoretically possible that a plague could strike the first born: if all the other plagues had taken place (frogs, lice, disease, etc), disease could settle on the top of grain; the eldest child would always be given the first helping of food, so it's possible the first born would be killed. But again, is is all theory.

One of the added struggles is the fact that there are differing theories as to when Exodus happened. According to a rabbi I consulted from Chabad.org it happened in exactly 1312 BC according to the Talmud. But Biblical scholars place it as between 1200 - 1250 BC or 1446 BC. The differing in dates comes from contradicting dates given within the various books (e.g. Kings)
