<i>If this is life, in a life-as-we-know-it sense</i><p>It&#x27;s much weirder than that; after all, there&#x27;s been life on Earth for at least 3Bn years, but space-going life for only the past 57 of them! Stack it all up: if this <i>is</i> some sort of life-created megastructure then it&#x27;s not just evidence of life, but of presumptively-multicellular tool-building life that can get off its planet and survive in an intensely hostile environment that it didn&#x27;t coevolve with.<p>With an estimated 100Bn stars in our own galaxy alone, this would suggest we can expect to see on the order of a million interplanetary-capable life forms in the process of carrying out mega-engineering projects, and yet <i>none</i> of them have come calling on us? Fermi Paradox calls bullshit.
