how the recorded history of man is only 2,000 or 3,000 years and yet we've been on this planet for 200,000 years

 

makes me think that there may have been great civilizations in that span of 200,000 years with similar technological capabilities as we have today

Actually we have history recorded for at least 6000 years. The jewish calendar year is around 5770.

To approach technology like ours they must have produced non-decomposable materials.

 

Also, we can track the progress of human technology quite well, seeing when we harnessed fire, developed tools, began agriculture etc.
