Syed,
Are you suggesting there is something very interesting about the fact that our brains are capable of such amazing inventions even though we aren't aware of this beforehand? I agree with you.
It is incredible that we are born with brains that are capable of such things we wouldn't believe.
Like Atheos and Ford said, if we take a caveman baby from 10,000 years ago and bring him/her to the year 2017 and raise them like a normal kid, they can easily grow up understanding computers and smart phones and space travel etc.
And why is it that caveman baby brain is so advanced with so much unused capacity they don't realise.
Maybe the same is true of OUR brain in 2017. Maybe we could travel forward in time to see astonishing (miraculous) technology and learn that it is not "supernatural" but quite natural.
Maybe miracles like Jesus performed can be understood only once our caveman baby brains travel forward in time away from our primitive, limited understanding (skepticism)
Well, that's just because the hunter-gatherers of that time needed to know a
hell of a lot more in order to survive the day than we need to right now. They needed to know migratory patterns, weather signals, plant botany, weapon making, shelter building and a whole host of other skills necessary to live while lacking any kind of medium to transfer this knowledge to the next generation beyond just telling others about it and having them remember. The kind of intellectual levels needed for that can be transferred to learning the information needed for our society as well, which is far less complex and involved for most people and gives far less consequence if you and the people around you don't know it personally.
