There are a lot of unanswered questions. Personally I like to look at more recent history because I think they pose much more interesting then going back millions and billions of years. Like for starters it was mentioned humans have been around for 100K years. I think that number is off a bit. I recall watching a documentary some time ago which talked about the history of human evolution and tracing our linage back. Well new estimates as I recall put it back to more like 250K years.
So a more interesting question is even if you assume the 100K year number the question is what took us so long to develop technology? If the human remains they found do match modern day humans and show they would be similar to us then why did it take 100K years to develop into the modern technological world? Now I understand the dark ages and that knowledge was lost but that is only for a few centuries and were talking 100K+ years here were humans were as intelligent as they are today even if uneducated.
Interestingly the first civilization seems to spring up overnight. And it's not a simple one either. Do some research on the Sumerians. We get the 24 hour day divided into 60 minutes from them, 360 degrees in a circle, the first written language, and so on. In fact a lot can be traced back to them. Much of Egyptian knowledge came from them as Egypt roses out of the ashes along with many other early civilizations that we are more familiar with. Yet not much is ever talked about Sumerians.
So back to the original question of if people have been around in their present form and intelligence for at least 100K years then what were they doing for those first 90K+ years because it stands to reason at least one group should of developed technologically. It only stands to reason that someone somewhere would of developed the technology much sooner given our intelligence. It's like the story of when the laser was invented. Three different people in 3 different parts of the world all get the idea for the laser at about the same time be it a few weeks or months apart. But there still work on their own without any knowledge of each other or that the others are working on it.
So why not with farming, city development, mathematics, writing, and a ton of other things? Why only in that one place and why only after tens of thousands of years of humans being around? There were people all over the world at that point which has been shown through fossil records. And given human intelligence it's quite obvious that technology can develop rapidly in a very short period of time but it can also be lost just as quickly given war, natural disaster, or etc. This I understand and accept.
It does not explain however why humans waited so long to develop even the most primitive technologies when our bodies and minds had developed to the point they are today where we pretty much need technology to survive. And humans have been around for long enough to develop different physical characteristics that suit the local environment. Something that was estimated to take at least 20K years for each split. And is also estimate that if all global travel were to stop that in 20K years each region would return to the same ethnicity group that is associated with that area because of natural adaptation. Since things like skin color actually have a function such as effecting how much sunlight our body absorbs so that we can make Vitamin D while also preventing the break down of other Vitamins in our body. One of which actually effects woman and pregnancy. Though I forget the medical specifics.
