Somewhat hilariously at the same time we think there must be life given the 14B year old universe, we look for 50 years and say, huh we can’t find anything so something’s wrong.. like sure our initial assumption was that a super powerful alien race would blast a powerful signal that would tell us how to contact them — and this signal they have been powering for millions of years ? — that would be great but seems like that isn’t happening. So likely we need to just keep searching.
