I don't think the ancient world, especially very cosmopolitan places like Egypt, were a single people that can be traced as a single lineage all the time. Ancient Egypt was around for thousands of years and comprised of various people that would flow in and out.
Also tracing lineage back to literally 4500 years ago is tricky enough, because eventually everyone's related. I'm a typical white American and I wouldn't be surprised if 4500 years ago I had ancestors from Libya or the Levant or even ancient Egypt.
