people retell the story of their people who witnessed the creation of an important being known as Budj Bim, one of four giant beings who arrived in southeast Australia. While three of these beings strode out to other parts of the continent, one stayed in place; that was Budj Bim. His body transformed into the volcano later given the same name, and his teeth became the lava that transformed the landscape. Theories and Disagreements In 1878, Robert B. Smyth, a mining engineer and geologist, raised a question on how Aboriginal Australians get fire. He agreed that there were active volcanoes in Victoria; however, he claimed that there was uncertainty as to whether people actually inhabited that land. However, it was later proven that Smyth had an incomplete idea of Australia's geological past.
