    Or they’re the things 99% of people are calling ‘aliens.’

    Why an interstellar species would travel light years to come to this pale blue dot in ships that don’t really interfere and look like our own just a few hundred to thousand years more advanced is kind of hand waved away.

    But if those sightings are in fact accurate, it sure seems like our narcissistic species would be pretty interested in our past selves once the tech existed.
