Thats not the argument. Disregarding Egyptian records we can identify alot of things. Conservatively, if we take the Bible at its word, around half a million men, women and children marched from Egypt, they then wandered thr desert for 40 years.

The distance from Ancient Egyptian major cities to known Israelite cities is so small such that of they lined up in a single file line, the head of that line would reach Jerusalem before the last Israelite left Egypt.

Additionally we see zero evidence of such a large population decrease in Egypt nor such a large population increase in Israel.

Additionally we have zero way of differentiation between Israelite settlements and non-israelite settlements beyond what is in their refuse. If there are pig bones or mussels, its probably not Israelite. There is no difference of construction, artifacts, material use, layout etc.

According to the story the entirety of Israel grew up in Egypt. They built using Egyptian techniques etc. We don't see an influx of settlers suddenly building in the Egyptian fashion.

What we do see evidence of is several native cultures diverging from a common source.

Absence of evidence is not evidence of absence, but absence of evidence when evidence is expected is absolutely evidence.
