Your series takes a particular interest for me in this post, @dedicatedguy, because you pose two hypotheses that attract me. I am referring to the last two. The assumption of a super advanced capacity of communication by information transfer works as a hypothesis of great relevance, because it would put us in the situation of a type of non-physical communication; what could be happening for a long time and not realize it. I am also motivated by the hypothesis that terrestrials are a recent existence in the universe, which, first, places us in a non-exclusive original condition (almost proprietary, as some may believe) and also opens up very broad possibilities for thinking about our future. Thank you for your thoughtful post, @dedicateguy.
