Even other animals have the concept of land ownership. They might not use our words, but see what happen when you take resources from the territory of a bear or other territorial animal.

Even trees do that. Eucalyptus literally poisons land near it to kill competition.

That’s occupation, not ownership. Ownership can’t exist without a legal or cultural structure to enforce it. A human can occupy land and defend that occupation with violence but that does not mean they own the land. A society can exist without ownership.
