So in essence you are saying, I can offer a theory which I cannot prove. I ask you for data that will disprove it. I can not prove it yet. But I do hope that the future will bring me a successful prediction. That is what the predictions I told Jim Bell about are for.
Successful predictions are the way science works.
If a form of Homo is found far back towards the 5.5 myr range, then I would consider that a successful prediction. No other Christian harmonization offers prediction. We seem to run from it for fear that we might be proven wrong. I might be proven wrong but we can not run from it. Then we have theories built upon theories.
