I have a related question : if we set up sensors a few light years away capturing every signal it is possible to capture by our tech (the full electromagnetic spectrum). And then if we put all this data into an anomaly detection algorithm, will the Earth stand out? Based on the data that we capture, are we actually special? The reason for anomaly detection (unsupervised) alg is that it doesn't have any of our subjective biases. The answer can give evidence for whether seeing signs of interesting planets is actually sign of life or not. Thoughts? I don't think Earth will stand out based on the information that will reach tens of light years away.
