"What about statements like 'this is their land' which places human civilization in a position of ownership over land above that of nature/non-human animals/etc?"
Which you answered perhaps inadvertently by opening with: "The state of Israel is an occupying force on the Palestinians and 'their' land."
All states begin with the consolidation of a military and/or police force, usually despite or contrary to any desire from the population who are living in the area at the time. Some folks may want a state, some may not, but most are probably indifferent.
The situation in Israel/Palestine is especially ugly because of Israel's decades-long position as a US client state that often refuses to accept the soft nudging of the US State Department. As a non-Muslim wild card surrounded by Muslim-dominated polities, Israel gets to run roughshod over much of the region with little thought to possible international consequences due to the US's ability to veto any UN Security Council resolution.
