Hey guys, what are your thoughts on the existence of extraterrestrial life and the potential involvement of governments in concealing or studying such entities.

I’m not saying we are the absolute first, as in there’s nobody else, I’m merely saying that we could be among the first civilisations ever to exist. To me, it seems a more plausible explanation than civs just going dark. As far as we know, there’s no way to take back a broadcast that has been travelling for centuries, so even if they no longer send anything, what they sent in the past should still be detectable, I think, unless it didn’t have enough time to travel here. In which case, the broadcast has been sent relatively recently (no more than a few millenia ago) or we are very far apart.
When you go to a party and you don’t see anyone else there, you don’t think “Everyone must be hiding”, you think “I must be first”, right?
Broadcast degrade, which wouldn’t mean much for already existing conqueror civilizations looking for anyone to invade, but does mean the signal isn’t entirely endless and we don’t broadcast with the strength to reach very far (what with our only needing to send them around our planet). Our historic signals may very well never make it to civilizations advanced enough to hear them just due to distance and the fact that space isn’t a perfect vacuum; signals degrade linearly as they are overwhelmed by the comparatively much more powerful background radiation. Digitally encoded signals like the ones we send now would be even harder to detect as the information would seem random.
Additionally, if we were to stop broadcasting then our broadcast would be effectively an expanding bubble with a ~130 light-year thick surface, so while it may reach a civilization and continue to reach them for 130 years, there is a chance it would reach them prior to technological advancement and it would pass by without detection. Of course in this case we assume that a new civilization would be hostile.
The party example doesn’t really work here because there is no start time to be on time or fashionably late/early to.
Fun conversation, this is the stuff I used to love reddit for 😊
