Given the rate of technological advancement in intelligent species, any intelligence with as much as a million years head-start should be engaging in engineering on a galactic scale by now. We should be able to see their public works projects from here.
For some time I was entertaining the thought that Globular Clusters were indeed ARTIFACTS. Since then, I have realized that they might indeed naturally occur - as certain astronomers have tentatively begun to understand.

Ho ho ho ho.
