You really don't seem to understand why you are wrong.
Let me try an analogy.
How far back can we push the invention of the spring-powered pocketwatch?
You seem to think that we can push it back as far as we like. But we can't. A spring powered pocketwatch needs springs, so the spring powered pocketwatch must have been invented after the spring was. If we push the spring powered pocketwatch back far enough, soon we'll have to push back springs. And we need a manufacturing process capable of producing the small components needed to make a pocketwatch. So if the spring powered pocketwatch is pushed back far enough, we'll have to start claiming that people developed the manufacturing process earlier as well. And since the spring powered pocketwatch is made of metal, we need to have the capacity to produce metal before we can have the spring powered pocketwatch. But if we keep pushing all these things back, then it's going to cause a problem, because we'd get to a point where you are claiming people could have had spring powered pocketwatches, yet all the evidence from the real world shows they were still just making stone knives and dressing in bearskins.
