If "it" is there and is indeed the cause, the investigations should eventually lead to it, or produce more evidence that it exists whether you started of specifically looking for it or not.
“If “it” is there and is indeed the cause, the investigations should eventually lead to it, or produce more evidence that it exists whether you started of specifically looking for it or not. “
The fact that “it” is the only known source of information observed to date, together with the lack of any credible naturalistic explanation, is pretty strong evidence, at least to me. Things may change, but my only point in this whole discussion is that we have observed to date where information comes from (intelligent agents and only intelligent agents) and this should be on the table. It is our best “known” explanation anytime we see complex, specific information.
I assume that complex, specific information is what SETI is looking for and assuredly if they find it, we would acknowledge an intelligent source even if we could not define or identify it. Yet this would be considered scientific and would surely be on the table as proof of extraterrestrial intelligence.
