> those who are Islamic today but whose genetic ancestors practiced Judaism in the past and lived in the historical kingdom of Israel have far greater claim to the land

Broadly speaking, any philosophy that rests on an oldest-claims-first metric are guaranteed to cause violence.

Information degrades the further we go back; you’re prioritising the wishy-washiest sources of truth. And the nature of human migration and interbreeding means the further you go back, the less likely you are to find genetic ancestors of the people who currently control the land. The people alive on the land you want them off. People with guns.

(The theory is also fundamentally based on the notion that racial migration is wrong. Immigrants to America have less claim than white Americans, who have less claim than natives, except for all the natives who were conquered each other because they moved around too.)

It's not about the certainty of the information. The fact is that humans have always and will always migrate in large numbers for a vast number of reasons, and these migration movements are the main sources of cultural and linguistic change. So, any ideology with historical justification, based on how people in a region lived a long time ago is going to create wars because other groups lived there at other times, and ethnic and linguistic groups constantly change and evolve. Named regions, ethnic group boundaries, countries, and their delimitations change over time.

> The theory is also fundamentally based on the notion that racial migration is wrong.

There are no human races, though, at least not ones based on phenotypical traits. Genetic analysis can reveal indications of regions and ethnic origins but these are barely linked to phenotypical traits and cannot be inferred from the latter. Linguistic communities are the bearers of a shared culture, not anything related to the bogus and outdated concept of "human races." It's also worth pointing out that the claim that "racial migration is wrong" does not follow from any of the other considerations, nor is it needed to support them in any way. I suppose you meant to say the opposite, that the view that racial migration is wrong cannot be morally justified because historical justifications are wrong? Otherwise I don't get the final remark.

Race is a social construct. That doesn’t mean it isn’t real. The constructs of “Israeli” and “Palestinian” are as real and deadly as the geographical boundaries they each draw.

If one’s ancestors define legitimate claims to where one can live, then one cannot legitimately live where one’s ancestors were not. In a weird way, the historical returners do a full swing to the xenophobic anti-immigrant types. (There are people who I’ve heard seriously argue that accepting Palestinian refugees is literally genocide.)

Exactly. Otherwise, anyone could claim anything since we all share the same ancestry, going back to the same primates or something[0]. We should focus on the issues at hand and work to avoid making the situation worse. Forcing all Israelites or Palestinians to leave is not a feasible solution. The problem needs to be addressed through peaceful negotiations and immediate support for those in need.
