Greetings! If for some reason humanity in general were to conclude that it is most likely that there is metabolizing life of a large or small range of size and intelligence on other planets, what are the justifications for spending such resources, public or non, for the search? For instance, after my own lay research into the question, I’ve settled with the opinion that E.T.L. is more likely than it is not. So personally, I don’t really have a good argument for continuing the search if the rest of us humans were able to accept we are probably not alone, therefore we are not so special, therefore…; etc. This is not a barbed question. Just curious to hear what others have to say.
