As podcaster Scott Adams would say, there is simply no “payday” for these people in recognizing what makes us, as humans, unique.
As every medical student comes to learn when first dissecting the human body at medical school, our limbs are almost entirely composed of muscles.
Only an organism of our dimensions and android design — 1.5 to 2 meters in height with arms about 1 meter-long ending in manipulative tools — can handle fire.
Being terrestrial is one obvious requirement. No fully aquatic species could master fire and thus develop metallurgy.
Without this ensemble of fitness in nature, there would be no wood, no fire, no metallurgy, no modern technology.
