I liken it to the story of Noah. Whether that was the mediterranean re-joining the Atlantic and thus oral re-tellings from a much much earlier event or merely a localized flood you can certainly imagine someone preparing for a flood and surviving localized or wide-spread destruction. But two of every animal? That's not a stable genetic population. Hell there are 40,000 or more species of spiders! There is simply no possibility that you could even fit enough animals on a boat of any kind to make that story work. If it did happen the immediate result would be complete genetic collapse and extinction. The idea is abject nonsense but the core story probably happened.

It is easy to imagine a large group of slaves escaping or being freed from Egypt. Maybe they or their ancestors were war captives. But wandering the desert for 40 years? Yeah right. Even if you want to grant miracles the idea that all of Egypt would even know about such events at that time is bananas. Information didn't travel that fast. Probably one group of people in one city. And the antagonist could easily have been a local lord. Over time it became the Pharaoh and the 18 months of wandering turned into 40 years. Only then it was written down.

I would also note that there were things like the weird restrictions on fabric and clothing which make more sense when understood not as something an omniscient divine being cared about but rather as part of rabbinic politics where the central temple rabbis were saying that their political opponents in the villages dressed wrong. It’s very easy to imagine a trip through the desert being bad, losing people to lack of food or water, but then being magnified in the future to claim divine superiority or strengthen arguments that they had earned land occupied by someone else (similar to how American western settlement sometimes justified ignoring native claims by saying that the suffering and lives lost in some way meant the survives had earned the land they ended up on).

It could also be that saying "wondering the desert" sounds better to a farming population then "they lived as nomads."
