lindelof and scott limited imagination

personally i think lindelof and scott suffered from very limited imaginations maybe the curse of being older people but are you telling me after getting a 100 million year headstart on humans our present day technology is almost similar to the space jockey engineers. with that much of a headstart compared to humanity you'd should have been at true god status by now. i mean it took like 2100 years to go from donkey and cart to intergalactic ftl space travel, assuming another 1000 years we would be at space jockey level technology, but within that time their tech never advanced...i mean really? they could have gone completely wild with futuristic concepts that are thousands and thousands of years ahead from what currently exists in the movies timeline, like...engineers developed a way to bypass death thru...mixture of nanotech rebuilding and dna, so if they are are destroyed they could just come back slowly, like a biological version on the liquid metal terminator.(now thats advanced) instead wwe got "yeah the space jockeys are advanced but we humans happened to catch up with them, despite them having a million year headstart?"
