Create a highly realistic video featuring three characters: a Heidelberg man, a Heidelberg woman, and a Heidelberg child, all depicted as early humans. The setting is a dense, prehistoric bushland with a variety of trees, shrubs, and natural elements typical of the era. The characters should be walking together through the bush, interacting naturally with their environment. Heidelberg Man: Depict him with robust physical features, including a strong jawline, broad shoulders, and muscular build. He should be wearing simple, primitive clothing made from animal skins and carrying a basic tool or weapon, like a wooden spear or a stone hand- axe. His hair is long and unkempt, matching the rough and rugged lifestyle of early humans
