I was listening to a video talking about archeological evidence for the faith and cited a video covering this discovery from a few years back. Atheists and skeptics of the Bible have used the lack of obvious evidence for the existence of the Hebrews in early Egypt as a kind of proof that the Biblical passages are more legendary than historical. In Egypt, there was a Semitic people called the Hyksos but that is a very broad term that covered all the Semitic peoples living in Egypt like the Babylonians besides the Hebrews. Anyway, people forget that at different times other areas like Sudan were part of the Egyptian empire and can be used to substantiate such claims. Besides that, I would point out that the lack of evidence is not necessarily proof that something doesn't exist, not only is proof hard to find, and things get destroyed but the Pharaohs often wanted to erase some unhappy memories from the record of the past.
