This is a nonsensical question. History is not a march towards an end goal, or an elevation from 'primitive' to 'technological'. This would be like asking 'why no lizard civilization' or 'why no Chinese monotheism'. The things that happen are a succession of complex states and they bear no analysis of sequential 'achievements'. There is no finality. Lifeforms just hunt down energy sources and reproduce, and power structures in society emerge and dissolve. There is no finality, no ascent, no goal.
Edit: maybe in a couple thousand years we will have something like Mycenaean civilization but on the moon and with space elevators. Maybe a chain of volcanic eruptions will send us back to the stone age and in another dozen millennia another version of global civilization will have emerged, this time with oceanic floating cities. For all we know, given the amount of actual evidence and the margins of doubt, global civilizations might have emerged and failed 10 times before.
