Why did the europeans claim the land of the aborigines?

Europeans claimed the land of the Aborigines primarily due to the belief in terra nullius, which held that land not cultivated or developed by a recognized state was available for appropriation. This perspective disregarded the existing rights and cultures of Indigenous peoples. European expansion, driven by economic interests and a desire for resources, led to the dispossession and marginalization of Aboriginal communities. Consequently, this colonization resulted in profound social, cultural, and economic disruptions for Indigenous Australians.
