The First Technosignature

The first technosignature arguably was the LGM signal. We saw this signal was regularly, regularly pulse. But it turned out to be a pulsar because it was spinning at a regular rate. So that's the thing is whenever we see something that's mathematically precise, we think life intelligence, but nature can be mathematically precise as well. Finding a megastructure is the best chance we have in our lifetime of finding evidence of alien life.
