How does one refute something which hasn't been confirmed in the first place?
When Java man was found and after the pilt down missing link forgery, the evolutionist at that point of time beleived that these were the ancestors of HSS and HSS evolved from them so HSS could not have been around when these other hominids were around i.e Only one hominid per era. The modern evolutionists/Storytellers have long since dropped this idea and now openly acknowledge that multiple hominids could have co-existed and they have dumped the linear evolution tree. But even after the correction, tertiery man is still held to be impossible by the evolutionist.
Though their premise of discarding all the eivdence and forgetting scientific literature regarding evidence of tertiary man, has been wrong and withdrawn, they still stick to the conclusion.
