I like the idea that because we’re millions of light-years away, aliens looked into their telescopes and saw GIANT DINOSAURS ROAMING EVERYWHERE and said “we’re going to study this one from afar”

@FalloutUrMum

I like to imagine that aliens have enough of their own problems to deal with us right now

@matticus7584

I think it's far simpler than that. Consider the duration of which we've spent actively looking beyond the stars for evidence of other life in comparison to the duration humanity has been alive. Span it into a year, we've been looking for 10 seconds

@JasonB808

Universe is so large that millions of intelligent life forms can exist, but be so far apart that they each believe they are alone in the universe.

@ndknight

I like Calvin and Hobbes' take on it: "The surest proof we have that there is intelligent life out there is that none of it has tried to contact us."

Grabs a handfull of ocean water: "Nope. No fish here"

@wednesdayPrepper

assuming aliens need an earth-like planet is your first mistake

@strixytom

aliens watched our tiktoks and shorts and decided "nah this ain't it"

@floridasavannah

My favorite Cosmic Horror Story was when they got a signal from an alien species that told us to "be quiet or they'll find you"

@ElizabethWarrenYeahYeah

Nah, they've found us and realised we're not good neighbors, so they're swerving us.

@ponternal

The most boring explanation would be that planets with life are too far apart and that advancing to the point where they can contact each other is impossible.

Great Filter: Species must overcome its own greed, and not destroy its own habitat.

@CantankerousDave

Two words: time and distance. Folks just don't get -- really GET, deep down -- how vast space is, how slow the speed of light is in comparison, and time at cosmic scale. Intelligent life probably rises and falls all the time, but the odds of it happening at the same time and for that life to be close enough to detect each other and figure out how to communicate are literally astronomical. It's like what's happening with Betelgeuse. The dimming and flaring we're seeing actually happened 642.5 years ago, but we're only seeing it now because light is so pokey. If the star went nova today, we wouldn't know until 2665. The nature of the space-time continuum itself is the real filter.

@PhoebusApollo14

I like Hank Greens idea that if a species gets advanced enough to know how to explore the stars, they learn its more important to just be happy, and don't.

@aggressivelyzoe

this is why i’ve always been totally fine with us not finding aliens lol. if we find them there’s a greater chance the great filter is ahead of us rather than behind us

@Potatinized

Can you imagine creating all these weird non-sensical designs for alien, and when we really do meet one, they looked exactly like us?

@artypyrec4186

I like the dark forest theory. You don't know what's in the dark, either you're alone or you're being watched

@kaynineteen3356

"Sometimes I think the surest sign that intelligent life exists elsewhere in the universe is that none have tried to contact us". 
Calvin and Hobbs.

@standardrobloxian7212

The most terrifying theory for me is the dark forest theory. It just creeps me out that there may already be a civilization after us because we are lighting us up like a Christmas tree to any alien civilizations
