My issue with that has always been. Ok, alien beings have developed the ability to travel across the galaxy. Pretty high tech stuff right ?
Travel at or near the speed of light ? High tech metals, composites and whatever.

Why would they fly how ever many light years, stop by our little bump in the ocean of the galaxy and say ok team let's revert back to our stone age and see if we can still throw a bunch of rocks into a big pile ?
