Cranial morphology: I did quite a bit of that in grad school. Of course its subjective, but if you are suggesting that none of the observations are accurate or that anything subjective is automatically wrong, I would have to strongly disagree. I would request that you back up your conjecture.
DNA: Actually, DNA affirms common descent and a lot of the critical details of evolutionary theory. Darwin could have been proved wrong, but he was not.
"resulted in fakes more times than not:" Not a true statement.
"Piltown man strike a bell:" I am familiar with the Piltdown hoax. Most anthropologists dismissed it because it did not fit. Friedrichs and Weidenreich had both, by about 1932, published their research suggesting the lower jaws and molars were that of an orang. They were correct.
"many of the skulls in the series were not even found on the same continent:" So? Early man got around, just like we do. But most were found in Africa.
"may be of children or mutations of same species or adults vs children:" Or may not be. Study some of the fossils before you opine. Do you really think that we can't tell a child cranium from that of an adult? The Taung cranium was a child, Mrs. Ples was an adult (see the text which follows; I have actually studied casts of both specimens, so this is not all second-hand).
"too much we do not know about this attempt to use fossil records inappropriately:" Not a true statement.
I find your responses most unconvincing. You clearly have not studied evolution as much as you have opposed it.
In the specimens below, not the cranial morphology and the differences between a child and an adult.
If you have any questions, let me know.
Fossil: Taung Child 
Site: Buxton Limeworks, Taung, South Africa (1)
Discovered By: M. de Bruyn, 1924 (1)
Estimated Age of Fossil: 2.3 mya * determined by Faunal & geomorphological data (1, 4, 5)
Species Name: Australopithecus africanus (1, 3, 7, 8)
Gender: Unknown (1)
Cranial Capacity: 405 (440 as adult) cc (1, 3)
Information: First early hominid fossil found in Africa (7, 8)
Interpretation:
- Juvenile (3 years old based on deciduous teeth, first permanent molars) (1, 3, 4, 7)
- Bipedal hominid (based on position of foramen magnum, brain endocast, small canines) (1, 3, 4, 7)
- Killed possibly by bird of prey (based on fractures and puncture marks on skull) (1, 10)
