Re: What was there in the world 10,000 years ago?
I agree with what TLK has stated, but also with what muqawwee123 stated. Assuming we go by the Historians ...
First there was nomadic life - this meant the people would usually wander in smaller groups, the leaders being responsible for only a hand full of people. Then families would probably bump into one another and enquire from one another about food sources, then they would work out seasonal variations and instead of travelling haphazardly they would return to the same places and travel nomadically in cycles - similar to the migration patterns of birds. This meant they were more successful at survival and could sustain larger families.
Then they realised that food could procreate through plantation and would encourage the growth ... They also realised water was needed and developed irrigation. It was probably to onset of irrigation that enabled people to settle ... the first settlers in Mesopotamia did so probably because the region never dried up - it was naturally constantly irrigated.
The development of technologies meant complex forms of communication were needed and people were probably developing the first forms of trade at this point. With the onset of value, security and protection was needed. As the settlements grew the reign of leadership and the influence of a few over many became more and more significant ... Verbal comminucation was not enough to carry the message of instruction to the people. Memory and tutelage was also not enough - because as settlements grew their interaction with other settlements meant some of their more seasoned minds would die, or be killed ... They developed a sense of sustainability and record keeping which they did through counting and measuring quantities of foods, trade items, weapons and these developed into images of the same things rather than those things themselves ...
The formation of society and community accelerates population growth.
***My personal opinion is that Adam (AS) was taught all of these things - science, languages and written forms were part of his legacy ... and we are merely rediscovering these things ... after years of forgetting them and rediscovering them.
***Everything will perish ... The problem with history is that it is a snapshot in time ... our time ... the recorded history is only an image of what remains ... We have no idea of what extent populations had existed in the past and how intelligent they were because certain catastrophic natural events take that "reset" the history we don't see.
For example ... if a rift opened out under a village and it fell into a sea of magma all the living creatures and houses and any tools would be totally turned to magma recycled rock formations - never to tell the tale of history. It is inevitable that the further we go in the past the less information we can obtain because it has longer to be destroyed ... "history reset" ...
We know that latter writings were on papyrus those papers have on the whole vanished/disintegrated ... inks would fade so we have older writing that is more intact - i.e. stone engravings than the slightly newer writings. For sure there would be stones totally destroyed and recycled by the earth that may have had older writings on them.****
