This is worth at watch. The speaker believe that we've made it past the Great Filter and thinks we may be the first.

It certainly seems more and more likely that we are alone, at least in our galaxy. This makes mre profoundly sad and does keep me up some nights.

Well, there are far more possibilities than the ones listed above. It's a fun thing to ruminate on. For one thing, we don't yet have a clear concept of how "life dense" the universe is, let alone "civilization dense". The universe is kinda big... from a cosmic scale, the galaxies may appear to be peppered with life, but at our local scale, those spots are too remote from us locally to identify, primitive or not. I kinda like the idea that we and our (hypothisized) neighbors are all on a similar "clock" having our solar systems formed at a relatively similar time and similar way (if they exist at all) with life evolving more or less in tandem give or take a few thousands of years... but that few thousands of years though... say there are 3 "living" planets approaching a sophsitication where they can start broadcasting in our proximity.... that made-up margin of thousands of years (which is small considering we are talking about planet formation, biogenesis, evolution, etc.) is still a looooong time on the human scale. I mean, how long have we been sending signal? It's all speculation... but I think the reality is there aren't any integalactic, massively advanced civilizations nearby, even if they are ignoring us... I think tech on that scale would stand out. It's a distinct possibility that we are just the first ones to show up at this particular block party.

Sentient intelligent life will eventually destroy themsevles. We will eventually destroy ourselves with our technology; weapons of mass destruction, pollution of the atmosphere, ruining of the ecosystem. If you think not just look at the major countries leaders. Hopefully the Earth will still be here and let the cockroaches take over, nothing can kill them.

The Fermi Paradox, although poses an interesting question challenging the existence of aliens, cannot stand up to the numbers. It's far more likely that life exists elsewhere than the likelihood of there being this big vast universe with trillions of stars and planets but they're all dead except all the sudden we happened. If it was just us, we would be the biggest fluke of nature in the entirety of existence. I don't think we're that special. So there's probably aliens. They're just too damn far away.

look up 'Great Filters' to see the possible explanations to the Fermi Paradox.

The probability of aliens existing is to high for us to be alone in the universe. Based on the fact that we have been unable to figure out how to transverse the universe successfully--and only having that information to go on--I'm of the opinion that other beings have had a hard time trying to figure out how to do the same.

According to President dumbaas we are up to our butts in alien, and they are ruining our country.

I do get a kick out of how this guy keeps evolving more into the looks of a mad scientist.?

In an infinite space I think it is impossible for there not to be all kinds of other life out there of different evolutions, capacities, capabilities and sizes etc. I think it would be close minded not to assume there are many possibilities. I don’t really know if they are here or even give a shit about us, but it makes for great fiction and movies.

Aliens are in the minds of those once created god... they simply moved on and on.... to the next and the next and the next.

Used to believe for a while after indoctrination by Chariots of the Gods.
