OK. A summary: Geological history of Earth - WikipediaThe point in my topic: there was needed time also for the evolution of the planet in many aspects so if there was any evolution of animals, you have to sum up all those periods in total to be objective about the appearance of all kind of living things: all kinds of microorganisms, plants, animals, ... and alleged hominids.
So what's your point?
I'm not following, Eli.After that you need to analize the time needed for those hominids to become what we are today or more exactly what we've being for about 6 millennia, with cultures, languages, knowledge of all kind of aspects of nature, arts, etc. ... Curiously there is not known evolution of human knowledge before the first known civilization: it was just there and nobody tells how it appears without especulate about everything, but without any real proof of that other "evolution": the human intelligence.
That first civilization had mathematics, astronomy, engineering, early childhood education, knowledge of agriculture, metallurgy, etc. Where all that came from?
Sum up the times. Again: something is not adding up.
Anyways, keep talking; I am reading you.
Have a good one.
Hominids have been around for a long time. For most of our history we lived in small bands of hunter-gatherers. We had no writing to record and accumulate knowledge. We did not specialize, and we owned only what we could carry with us. We lived day to day, season to season.
The development of agriculture and animal husbandry at the end of the last ice age enabled permanent settlements, accumulation of goods, increased population, specialization, and a social hierarchy.
I still don't see what "isn't adding up."
