I don't know enough about the subject to consider myself knowlegeable to be honest, I was merely looking at it from an engineering perspective.
the core fundament of engineering is problem solving, finding the simplest, most effective solution to achieve the desired end result. that applies just as much 5000yrs ago as it does today, and ramps, scaffolding, and plain hard graft seems to me to be the simplest solution.
by I go by evidence, and have no problem changing my stance on a subject when i'm given better evidence, even if it's totally at odds with my current viewpoint, which is the main reason i'm on this site,
