Composite photography when we have DNA?????
You have got to be kidding!
Have you ever studied Neanderthals, or evolution? Or forensics?
DNA is pretty good evidence, while things like you suggest are so subjective they are pretty much useless last resorts.
THe photo idea is just a starting point. Naturally I’d like to see the same thing attempted with DNA fragments of current living humans.
Likewise, scientific belief does not constitute a religion, or faith, unto itself
