This question was closed as "not focused enough" (How can an alien civilization be so powerful that it can with almost 100% certainty destroy any other civilization without getting a scratch?). One of commenters said
Your question is unclear. Are you asking about the mechanical methods they use? Are you asking about their fundamental philosophy? Are you asking why they haven't been stopped yet? "How" is ambiguous. Others have also made the same statement about the lack of clarity in your question. You may have rolled several questions into one. Please consider resubmitting a new question with more focus and detail clarifying that question
I'm genuinely puzzled by such statement. For me the title says it all, it has only one question and the question is so clear, that failure to understand it looks to me as failure to parse plain English. So I was quite suprised to discover that there are at least 5 people for whom the question was too vague. So it's basically situation: "You question is too vague, I don't understand the point of your question", "And I don't understand why you don't understand my question, it's perfectly clear".
To be honest, the question that I asked on Worldbuilding isn't important to me (and I already got some interesting answers), so I'm okay if it stays closed. I ask here because I'm anxious about my failure to communicate my thought and even more anxious by my inability to see what I did wrong. I have no idea about how other users misread the question that they got such wild ideas about its meaning as "It's about how God Seekers murder other civilizations", "It's about fundamental philosophy of God Seekers", "It's several questions rolled under one title".
P.S. How about this formulation: "How did an alien civilization come to be so powerful that it can with almost 100% certainty destroy any other civilization without getting a scratch?" Is it clear now?
