its funny how theres always an assumption that the aliens will have immensely superior intelligence and technology to ours, and would invade our planet with weaponry that relies on principles we havent even thought of. any alien civilization on another planet very likely wouldnt be much more or less evolved than humans, and are probably struggling with their own problems of disease, strife, social issues and religion to worry about using enormous amounts of their resources to mount an expedition around the galaxy looking for other life inhabiting planets some 1000 light years away
think about the odRAB of that happening, even if there was a planet every 1000 light years apart in every direction with inhabitants as evolved as humans give or take 10,000 years. so thered be inhabitants 10k years more advancesd than us, and planets 10k years behind our level, most on an average of our level. could humans in 10k years be advanced in physics, wealth and unity enough to make a successful 1000 light-year trip to another civilization? and how lng would that trip take?
