The answer is always going to be “it’s complicated.” Your mental model is vaguely correct but hinges on a lot of semantics and nuance - the timing does actually matter to get a full appreciation. The oldest evidence* of modern humans (Homo sapiens) is about 300,000 years old. “Archaic humans” generally refers to a group that includes neanderthals and some other species, the oldest evidence being maybe half a million years old. First evidence of fire use is over a million years old. The first stone tools are over three million years old and predate the Homo family of species altogether. However the point where our ancestors diverged from chimpanzees was over eight million years ago so “primitive humans” if you will have a very long history. In that time, primitive humans spread everywhere in the old world. Earliest evidence of tool use in Indonesia, for example, is on the order of 1.8 million years old. At that point the world was in the middle of an ice age and sea levels were much lower so Indonesia was part of the supercontinent and not an island. The oldest evidence of migration to colder climates is 800,000 years old. Our ancestors had already colonized the Old world several times over by the time “humans” left Africa. It really depends on where you draw the line between “humans” and “hairless monkeys” * Archaeological evidence survives and is discovered completely by random chance so we could be off by hundreds of thousands of years without straining credulity
