So what would a human do ? I think matches are very close to gun powder but I would have a hard time finding sulphur, potasium nitrate to make it and without looking it up, I don't know the proportions either. And frankly, it took humans a really long time to discover gunpowder.
No one is saying a chimp is as smart as human. What these people are saying is that humans and apes are not that far apart.
Matches have been used for gunpowder. Can’t remember if it was Robert Ruark or Peter Capstick who told the story of having to go after a bull elephant that had been wounded by a local villager with a homemade rifle using matches as the powder and a short piece of 1/2 inch rebar as the projectile.
And I am saying the God has has declared it an immeasurable gulf. Apes have no spirit. No spark. They are bereft of grasping the concept of eternity. Man is further from Ape than light is from darkness.
