Obligatory XKCD: https://xkcd.com/638/ https://xkcd.com/638/ I completely agree. We haven't been looking very long and very hard and we're not even that sure what to look for or where to look. All we can say right now is that we do not see any unambiguous signs of ETI, but space is called space for a reason. We are also searching the vastness of time. I don't completely dismiss ET-origin UFOs. I don't think there's anywhere near enough evidence to make such a claim as anything more than a hypothesis, but remember that one possible answer to the Fermi paradox is that there isn't one.
