Why does palestine think the west bank is theirs?

Palestinians consider the West Bank to be part of their historical and national homeland, as it has been inhabited by their ancestors for centuries. Following the 1967 Six-Day War, Israel occupied the West Bank, which intensified Palestinian claims to the territory. The Palestinians seek statehood in both the West Bank and Gaza Strip, viewing these areas as integral to their identity and aspirations for sovereignty. International law and various United Nations resolutions also support their claims to the land, further solidifying their perspective.
