Those pictures do not show very much development in alien technology while human technology have been enormously developed during the last hundreds of years. Perhaps aliens have developed technology longer time and therefore have better machines, but human engineers are smarter and faster. We will soon be the masters of universe.
I'm under no illusions that humanity is in any way smarter that whoever formulated the system of ancient cosmology. As an initial demonstration of that, the cosmology sees three processes of creation as having parallelism - how the universe forms, how matter forms, and how biological reproduction happens. The cosmology simultaneously describes all three processes using a single progression of symbols. Somebody is way smart.
