You make valid points about the limitations of using analogies and technology-based comparisons to understand the universe, as well as the vastness of space and the unlikelihood of encountering other technologically advanced civilizations. It is important to keep in mind that our understanding of reality is limited and constantly evolving. While science fiction may not accurately depict reality, it can inspire curiosity and further scientific exploration. The idea that we may be alone in the universe is a humbling thought, but it's also important to consider the possibility that we may not be alone and continue to search for answers.
