With millions of Earth like planets around sun like stars in our galaxy alone, why don't we see intelligent alien life? Or any other life for that matter? It gets especially weird when you factor in new scientific revelations that life on Earth occurred crazy fast! So if you want to help us theorize on the real reasons we haven't found alien life, you should watch today's episode of Space Time!

As Bill Watterson said : The surest sign that intelligent life exists elsewhere in the universe is that it has never tried to contact us.

[slamjammer]

Meanwhile, aliens are wondering the same question

[iamlsusam]

Because of the incredible distances between stars. It’ll take too long for interstellar travel to be practical!

[ronruba]

I've always been curious to know why we keep thinking aliens want to colonize... Because we would, we assume they would too???

[talonviperchef]

Humanity being the first generation intelligence? Oh my my the universe is fucked.

[ianbattles]

On a cosmic scale, time/distance are so incomprehensibly vast, the odds that any two civilizations will exist simultaneously AND be close enough to facilitate meaningful two-way communication are close to zero.

Even using our most advanced technology, it would still take longer than a human lifespan just to leave our own solar system.

When aliens fly by our planet they roll up their windows and avoid eye contact.

[vitast]

While I think it is likely there may be alien life, I believe intelligent life is probably even more rare. This planet has existed for billions of years, and intelligent life has only been a sliver of that time, appearing in one species. Most alien life is probably very simple or animal life. Either way, I would be just as excited to know there is any life other life out there at all.

I'm still searching for intelligent life on this planet

[danthefan]

When aliens fly past Earth they wind up their windows and lock their doors

[viggo]

Why is it always assumed that life must meet the same requirements as we know it on earth? for all we know there could be creatures who for instance dont eat drink or breath anything, but rather get their energy solely from thermal energy or radioactivity. We can never asses the general probability for life in space at all until we find and study the lifeforms on at least half a dozen different inhabited planets, if there are any.

Alien: “Commander, we may have found intelligent life.
Alien Commander: “ may have?”
Alien: “Well they’re developing weapons to destroy eachother & their planet.”

The scariest thing to find on another planet would be other humans

[DMS-pq]

Imagine if there were only five people on this planet, Put one in Los Angeles, One in Mexico City, One in Cairo, One in Paris and one in Tokyo What are the odds that one would ever find another? That is why we haven't seen aliens

[dermagrafa]

They want to talk to us as much as we talk to ants...

[sienielain]

The best explanation for this paradox for me is that, we are the first form of intelligent life in the universe.

[rakesh]

"300 million years, seems crazy fast" - its just like yesterday 😃😂😂

[jtlovestj]

Fuck, this is so awesome. the feeling of being the first sentient life in our galaxy is amazing.

We'd be the 'elders' of our galaxy if it were true.

[jonahjohnsen]

Either life is unique and we're it or they are all around us and don't want contact.

We could be so different that we have nothing in common.

"Marsians": humans have discovered our planet evacuate everyone to another solar system
"Humans": Dang it no aliens here
