It's been 10+ years since I watched it but Ramses II is the recognized timeline based on the Old Testament saying the Hebrews left that city. One of the things examined is an extensive archeological dig that shows the area was inhabited before it was called Rameses. So 'Rameses' had become a sort of colloquialism by the time it was being written about. Everyone knew what, or where, was being referenced, but the event itself actually happened earlier.
1. The current timeline has issues with various cultures tied to the period, not just the Hebrews. People like to say 'there's no evidence of thousands of people leaving' but if you move it to a prior dynasty things start to align.
2. The alternative timeline is a prior dynastic period (I believe it is the one just prior to the accepted).
Every time they claim "there's no evidence" they are just showing their own ignorance "I'm not aware of any evidence so there isn't".
They do the same thing for all subjects.
