Primitive man less intelligent than us?

Do you think "Primitive" man are far less intelligent than the humans of today?

What if a man/woman with the same "IQ" of normal humans today was born in a "primitive" world, without knowledge of anything but their own instincts, and the knowledge of the "primitive" humans around them. Do you think this person could accomplish more than the common "primitive" man could? Is our superior "Intelligence" just a illusion, since we never discovered everything we were taught, but that our "inferior" ancestors discovered, little by little?

Do you think YOU could discover the properties of fire/plants (farming) without previous knowledge of these subjects, just using your basic human knowledge? Do you think you could invent important things such as the wheel, wagon, irrigation and weaponry?

Do you think Billy Bob that lives down the street could discover fire if he, and no other human had previous knowledge of its properties? Do you think the young girl that served you your coffee at the local Cafe could? Do you think Stephen Hawking could?

That was a good post, but it has one flaw. People back then worked thousands, if not hundreds of thousands of slaves to death to build these huge monuments to attest their knowledge, skill and grandeur. That really makes them look "smart," doesn't it? Nowadays we don't whip slaves and work for hundreds of years to put up a huge piece of rock and then proceed to bow down in front of it and call it a god.

That's the real difference between ancient and modern man. We still have idiot religions, but not everyone worships large rocks. Or in other words, social ideas are more important than physical structures. If you can come up with an idea how to create such an impressively large building, and then use it to worship a statue? You kind of fall flat on your face in the evolutionary/intelligence scale.
