re: 10k year old megastructure found off German coast

So aliens made it all the way to Earth, and with all the knowledge they had, it only resulted in them using unhewn boulders to build with?



Humans were capable of building advanced structures longgggggg before we made it into space

Makes me kinda disappointed in our alien overlords. Maybe thats why they dont come back anymore. Theyre embarrassed about how quickly we surpassed them
