The ancient mind appears more intelligent and impossible to many present-day minds because it is actually more intelligent than most present-day minds.
The difference is, that the ancient mind was more intelligent in different areas than our present mind.
The present mind is forced to remember massive amounts of technical information, and by technical I am referring to the stream of numbers and words that populate our minds.
There are several pieces of information stored in our minds either only in word, number, or picture format and not direct observational format.
The ancient mind relied heavily on direct observational memory; far more than technical memory.
Because of this, the ancient mind also categorized memory into very large blocks of memory of the same event and all surrounding conditions of that event.
The present mind, being forced to remember such a large volume of information by comparison to what it used to attempt to hold, creates associative categories in the mind and then dissects any bit of information into it’s associative categories.
Meanwhile, the ancient mind, with it’s massive lump blocks of memory ran links from each block of memory that contained a thing in it that was also existent or related to some other thing in another large lump block of memory.
This is why the present mind recalls pieces of information, but not everything.
This is also why the ancient mind seems capable of holding very detailed pieces of information in their mind without using massive amounts of writings on paper for every person.
So, by comparison to long term memory, our present day brains are capable of holding far more information than the ancient mind, and do so far more efficiently for the volume we contain than the ancient mind would have been capable of doing.
In this respect, the modern mind is more intelligent.
However, the ancient mind had a much higher acumen than our modern mind.
It is for no other reason than survival.
Even today, we can see minds that are very similar to the ancient minds if we simply examine human minds that live in constantly traumatic environments where nothing is guaranteed.
The minds of this lifestyle, like the ancient lifestyle, is forced into concentrating on assessing as much information as possible in the shortest amount of time as possible.
The ability to do this is the difference between living and dying.
Even when not under direct threat, the fact remains that the ancient mind was focused on making something out of what lays near in their usable area that can be made into something that pushes survival further away from not surviving; defensively, or offensively; brutally or peacefully.
I would venture to say that the ancient mind, and the minds like it that exist today, are capable of assessing a third more information than they were or are able to transfer into long-term memory.
However, as suggested above, the information that is retained is kept in very large blocks.
This is only possible because of the extremely high acumen.
It takes high acumen with a need for all information and types of information, and for that information to be detailed information to create this mind.
The diversity of the need is because everything in the memory is a possible tool for survival, but the ancient mind simply doesn’t know what will be needed information when.
There is no ability to selectively hold information that may one day suddenly be useful information for survival in a circumstantial environment that the mind could not imagine.
Because of this, the blocks of information are linked, as suggested, from one to the other by associative observations inside of each bock of memory, and as the high acumen reaches each block, it assesses everything in that block in one solid shot and identifies needed information from it.
Sometimes, this produces suddenly new associations between two blocks of information, and so forth.
So the reason that the ancient minds seemed brilliant considering their environment is because their brains are quite literally far more raw human super assessing for survival than any modern societally provided for brain today.
They could assess their options and materials far better than today’s mind is able to do.
The difference, as I said before, is that today’s mind is capable of holding far more pieces of information than the ancient mind.
This means that we can communicate our ideas to more people over longer periods of time, and are able to separate observations into extremely detailed categories of information in our minds.
The end result is highly analytical minds that are capable of producing high levels of thought and design.
However, every time a great society falls…the ancient mind will pick up the race and be the leading mind of survival once again.
It will once again, build and expand things and ideas far more amazing for it’s potential than anything, considering it’s environments, than we can or will be capable of imagining if we hadn’t found it ourselves.
Here are a couple figures to help express the difference:
