Humanity has two giant collisions to thank for its existence, explains biologist Sean B. Carroll.
When an asteroid landed on the Yucatan peninsula 66 million years ago, it turned our planet into a debris field of chemicals that, eventually, fostered human life. Sean B. Carroll, author and esteemed biologist, unpacks the consequences of this collision, and claims we, as a species, should feel fortunate that we’re on this planet at all.
This historical cosmic event, paired with the tectonic movement of Earth’s plates and the initiation of the Ice Age, ultimately led to existence as we know it today. Without these random, chance environmental and biological encounters, the development of life would have been stunted, or even entirely nonexistent.
Even the sequence of human conception is random and unlikely, Carroll explains, leading us to reevaluate our understanding of evolution, true survival, and the significance of each individual life.

To me, he was quite clear on the matter, but I am scientifically educated and it took me years to learn the language scientists use. Perhaps start small. It’s not easy to learn another language. It maybe counterintuitive that the language is English, but science is not normal English. It’s medical English, there’s a huge difference. Also, get off this echo chamber. You are subscribing to linear thinking people and unconsciously self aligned yourself to the same ideology. If everyone has the same problem, it’s not the problem, it’s the people refusing to do actual hard work to attain knowledge.

This video prompted more questions than answers: How did the smaller animals survive without sunlight for three decades? In other words, don't smaller mammals /reptiles/amphibians need plants? How did they eat when there was no sun for about 30 years? Most multi-cellular organisms need plants at some level for survival. How or why does rock reduce carbon dioxide in the atmosphere? He mentions that the Himalayas reduced CO2 emissions which in turn created the ice-age. Also, how does an ice-age increase the size of our brains (relative to our bodies)?

[@weltschmerzistofthaufig2440]

The smaller mammals were burrowers, who already spent much time underground. Moreover, plants survived by evolving more resistant seeds and pollen, as well as optimising photosynthesis.

He answers how we got here, but why? If the probability of us not existing is much greater than the probability of our existence as we know it, what made the difference? His answer that this is all an accident is too simple for such complex events, it’s an easy way out, another way of saying, “I don’t know”.

[@Rickol91]

I understand your point of view but in some way every event can be both simple and complex at the same time for example: Someone died of a lightningstrike which is rare on its own but anyway .. If the newborn baby of the buss driver didnt cry all night, the bussdriver would have sleep well, he probably didnt fall because of his unknotted shoelaces, the buss was not canceled, The guy didnt had to walk in an open field.. then Boom!! You see what I want to point out?

[@JustennWolfe]

There doesn’t need to be a why. I think people when asking this question forget that we are a floating rock, orbiting 1 of trillions of stars. It’s not like all these crazy things that needed to happen happened so easily. It’s that we are just one of the lucky happy accidents stacked against infant possibilities. That’s why a “why” doesn’t, and likely can’t, be answered.

[@mandelbot5318]

As a few other people have commented, the chance of ME existing is 100%. The question “What are the chances of ME existing?” refers to a specific individual, ME. The question can only be asked, then, if I do, in fact, exist. In a world where I do not exist, no questions can be asked about ME, since those questions would refer to nothing. For this reason, questions regarding the chances of a thing existing cannot be asked of things with specified, unique identities.

[@TorMax9]

It depends on the initial conditions you are aware of and the point in time and your mode of calculation. Yes, you can come up with a probability of a future event. Bookies do it all the time. The probability that you come up with is not OBJECTIVE - because we can never include all the variables - but SUBJECTIVE - only including the variables that we can. Bookies often get it wrong and lose money. Stock brokers often get it wrong and lose money. Generals often get it wrong and lose the battle/war.. Once you do exist, it's 100%. Before you existed, it becomes increasingly small as you go back in time. After the football game has ended, who won is 100%. Before the game, different bookies will come up with different probabilities. Investors gamble all the time. Government programs gamble all the time.

[@FrancescoDAndrea]

The question is about the chances of a new born to have a specific genetic code. Like, "wha are the chances, if we throw 10 dices, to get the combination: 6431524316?" - of course, there are infinite gene codes only if we'll never end as a species - or if life will never end. Otherwise the question makes sense.

[@muhammedsaidcakir]

In order for the things to collide, they need to exist in the first place. If they exist, which they do then they must be coming from a source, since existence only can come from an existing being. So accepting the existence necessitates accepting a source of existence. It does not make sense to refer the existence to a concept that does not exist-like accident. There is existence not accident nor chance. So the existence of a source of this universe is more certain then the existence of the universe.

If we didn’t have a choice we’ll be robots and there won’t be no point to life. There is no good without evil, no light without darkness.And if everything was good and we lived in perfect harmony, no evil, no suffering, no pain, no bad, then we wouldn’t grow and learn.

Hey Big Think, I’ve been watching your videos through college. I’m in my last year of school. They inspired me to pursue a career in a psychology related field - Interaction Design. Can you please do a video on eating disorders? I was an extreme athlete for my teenage years until my junior year of college then I developed an eating disorder after a traumatic sprint of experiences. I don’t understand what’s happening to me psychologically but I want to return to athletics and nutrition without fear. I’ve been quite down for a long time - Despite being an ambitious student with strong leadership experience, career direction, a social life, and community. I’m hoping an expert on your channel can help bring me clarity. If you read this, thank you. I enjoy your videos thoroughly.

People are so quick to believe this because it sounds so interesting but ignore the fact that this are theories and we don’t really know.

[@theyomie5482]

Well first of all you must understand that the word theory in normal speak is much different than in science. In science our normal speak for theory is called a hypothesis. A hypothesis is a hunch, like what we all have daily, and a theory is a more scientific fact that has been substantiated by dozens of other people to prove that it is, in fact, correct. Now can that be subject to change if new information is discovered? Yes, but the core truth is still intact. Never before has a theory been completely erased once discovered, but new facts are found all the time, adding to it. It would be like if electricity or evolution turned out to be wrong. it just can’t happen because way too much evidence has been millions of times over substantiated by thousands of different human beings from all over the world.

This just brings me right back to the song "The greatest show on earth" by Nightwish which has this spoken section in it "We are going to die, and that makes us the lucky ones. Most people are never going to die because they are never going to be born. The potential people who could have been here in my place, but who will in fact never see the light of day, outnumber the sand grains of Sahara. Certainly those unborn ghosts include greater poets than Keats, scientists greater than Newton. We know this. Because the set of possible people allowed by our DNA So massively exceeds the set of actual people. In the teeth of those stupefying odds it is you and I, in our ordinariness, that are here. We privileged few, who won the lottery of birth against all odds. How dare we whine at our inevitable return to that prior state From which the vast majority have never stirred?"

But why am I here

[@salmankayani8095]

But the question is how life started from nonliving things and what about consciousness? we can explain the materials but unfortunately, there is no clear evidence of where life and consciousness come to make our material body evolve according to time needs. we can easily understand how we are born but how and who gives soul and consciousness to a body and the only answer is that there is a creator for all these.

[@thefamousdjx]

I hate when they pretend evolution is the answer to everything instead of admitting they dont know anything! They talk as if they all come to that same conclusion but no its driven by the same text books written by clueless people that made a lot of guesswork and passed it as fact

[@shawnstatzer95]

It is natural for people's brains to fill-in-the-blanks for missing information. It is often expressed via survival and can be tested and retested ending with consistent results. It is far better to not conclude anything without sufficient evidence and to just say "I do not know." Certainly, there is nothing inheritly wrong with searching for answers and throwing out some possibility, but to label things as facts when the facts are not known, is putting the cart before the horse.

[@TonyTigerTonyTiger]

Since humans don't have souls, your last part was meaningless

[@victoriadepew6863]

There is no evidence for a "soul". It's a philosophical concept not a biological one. As for consciousness I think that to we overstate. Consciousness is likely an illusion of our brain that evolved over time. We weren't magically bestowed with it. Life starting at all... well that does seem to be rare and hard.... but there is also a whole lot of stuff out there .

A CHANCE is a CHOICE; بخت and گزیدن are corresponding of these two words in Persian which is language of answers to all questions. بخت and وخت both mean time and rearranging of گزیدن letters will yield the word زندگی which means life. So, yes; everything is by chance which means they take place just in that arranged time.

[@alexgoslar4057]

Did it occur to you that the time and space correlation in the universe and for that matter, the multiverse, are entirely different from what we understand time and space to be? All we can measure is what the human mind can perceive, and that is insufficient for getting a better understanding of the universe.

[@Sleepparalysisdemon2]

I’m a licensed addictions counselor ( CACII) I have always told my clients that you have to believe in something. A higher power helps many people realize they are connected to something important. For many people, the journey toward finding a higher power is as beneficial as the addiction treatment process. As they detox from alcohol or other drugs, they become capable of thinking critically about the important things in life.

[@deenadamico2673]

No, it really doesn't necessitate a supernatural origin myth. Coincidence is the concurrence of events that have no causal connection. The way our planet evolved is no more the workings of magic than running into a childhood friend at a local store by happenstance.
