> as far as we know Therein lies the rub. "As far as we know." Human knowledge only goes back, what, 2000 years? Industrialization started, what, only 150 years ago? The printing press is, eh, 500 years old? Ubiquitous computers began... literally an instant ago in cosmic timescales. So while my argument might be summarized as "this one thing may be real because this other thing may be real but just 20 years ago wasn't even hypothetically conceived", your argument is basically "there's no way this one thing is real because this other thing is only distantly hypothetically real and still has flaws and besides, the whole concept is preposterous because there should either be aliens literally everywhere already or nowhere, because that makes about as much sense (maybe they're leaving our "incubator" mostly alone?), and because we simply don't understand how it's possible, despite the fact that we are basically 5 day old babies (and apparently VERY cocky ones) as far as science and human knowledge is concerned at cosmic timescales."
