When will the human species go extinct?

So I heard that 7.6 billlion years from now, the sun will destroy the earth. Do you think humans would still be alive by then to see it happen? Some scientists say it would take 5,000 years for all the ice to melt and the temperature would become way hotter Since humans only evolve 0.01% of our DNA every 100,000 years, I don’t think we’ll have enough time to adjust to the high temperature and the earth would become uninhabitable.

With the exception of possible pandemic and nuclear war that could wipe out humanity, and ONLY considering habitat threats like climate change, natural disasters and the sun destroying the earth, how many years do you think the human species have left on earth? Do you think we’d be able to live long enough until the sun reaches the earth and be burned alive? Sorry for the dark questions hehe.

If you’re a human who is living 7.6 billion years from now, comment down below😂

Edit: Hey everyone, thank you for taking your time reading my post and taking my questions seriously. I find this topic really interesting and it’s nice to know other insights/perpectives:)

Help us keep this site organized and clean. Thanks!

  • I think the human race will die out, simultaneously with every other species on the planet, when the world is destroyed. As for how the earth would be destroyed, it would probably be because of:
    a) a meteorite
    b) nuclear war
    c) collision with the sun
    d) pollution of the atmosphere resulting in inhabitable land

  • Humans will probably immigrate to another planet.

    • I hear that a lot. People say that once the earth becomes uninhabitable, we’d move to Mars, since it’s the most inhabitable planet other than Earth comapared to other planets. They said our technology would be so advance by then and it may be possible to move there. The only problem is Mars makes up about 96% of CO2 and gravity is only at 38% compared to Earth’s. We can’t even live 2 secs on earth without O2. And not only that but Mars also lacks many resources we need to survive.

      • No planet in our solar system is inhabitable for any large population. And the nearest star system would take 82 thousand years just to get to at our fastest current rate of space travel
        I think we better take care of the planet we have.

        • What about terraforming? With the technology we might have in a few thousand years, it's possible we may be able to introduce oxygen into the air of other planets. We may also find a way to exceed the speed of light for space travel. We don't know how much technology will advance in that much time, it's possible we could leave this planet well before it becomes uninhabitable. It's so far into the future that we can only really use our current technology, which is crap, or go off into the realm of science fiction.

          My "optimism" that humans will survive is based in my opinion that humans are like roaches. We can't die.

        • No, those are on Venus. It's 850 degrees in the shade. A tad warm but it's a dry heat. It's breathing in the sulfuric acid that's a drag.

  • All humans (on earth) will be dead within the next 52 million years.

  • The oldest homo sapiens remains that have been found to date are about 300,000 years old, and it's believed that our ancestors diverged from the Neanderthals about half a million years ago.

    There's debate in the scientific community about whether human evolution has come to an end because technology and social structures reduce evolutionary pressures to such an extent that even the least fit in terms of physical ability and intelligence survive long enough to reproduce. Even so, seven billion years is an unimaginably long time, and I think it would be very strange if the descendants of today's humans were indistinguishable from those alive now.

    I believe the intelligence and adaptability of our species could allow us to survive for seven billion years. However, I suspect that other aspects of humankind might mean we self-destruct in some way long before then. Also, the universe is not a benign place. There are lots of enormous lumps of rock whizzing around out there, and some truly catastrophic event with a global impact might happen long before the sun dies, and new diseases will always evolve.

    • I see. Do you also that think overpopulation would become the number one threat to our survival? When the ice melts, the ocean would become about 200 feet deeper which would force people to flee and move ashore (not sure if i said that correctly lol) Then we’d probably consider having fewer kids which would make human evolution highly unlikely since reproduction are the most important factor in evolution. I’m probably making things more complicated lol

      • I haven't looked into it, but my gut feeling is that while overpopulation might cause enormous suffering and widespread death, it's probably unlikely to make the human species extinct. There will always be rich, powerful people who can monopolise and control whatever resources are available, and you can be damn sure they'll reproduce.

  • We still got 5000 years to think or.. maybe i don't have to be married and adopt a child or two to save the world

  • My opinion:
    Extinct, no.
    But over time we could make this planet unliveable.
    However, folks like Trump and other 1% type will find a way.
    Either in bio domes.
    Underground.
    On a space station.
    Or another planet.
    For better or worse I don't see mankind going extinct.
    We have opposable thumbs, a brain, and a shit load of money.
    Most will die,
    many will slave suffer then die.
    But, that 1% will live.
    Make babies, and start the whole ugly cycle all over again.
    ( be a dick in comments if you must. It's just my opinion.
    I hope I'm wrong. )

  • We'll be the cause of our own extinction, no doubt.

  • The ai machines will destroy us well before any of that and will move from this planet and inevitably battle other inter galactic robots over resources.

  • We humans are just another evolved species that may or may not survive. Dinosaurs were the most successful species on the planet having survived and evolving for millions of years until an asteroid wiped them out. They may very well have survived if not for that but then we as a species would not have had a chance to be here.

    We humans have only been here a few hundred thousand years compared to the dinosaurs millions of years. We will just be another of earth's failed experiments unless we get our act together and find world peace and/or figure out how to travel light years to inhabit other planets and start over again as a planetary community rather than like little kids like we are now fighting for our own little corner of the sandbox we call earth.

    If we carry on the way we are now I see no long term future for humans as we will inhialate ourselves in a nuclear haulocost or pandemic.

    • Modern industrial civilization has only been around for a couple hundred years or so. And we've already ruined half the planet. I don't see a bright future for humans either.

    • Interesting. If our technology would be so advance which would allow us to travel to another planet, how are we going to survive in another planet? Our DNA is evolved in order to adapt to the Earth’s atmosphere and considering we don’t reproduce often, would we be able to fully adapt to a new planet, for example, on Mars, by obtaining the ability to be able to breathe CO2 instead of O2? You probably already know that the Earth was made up with mostly CO2 many years ago and the ability to breathe O2 was obtained by a single-celled ancestor, not the human species, so we don’t have the ability to evolve fast enough to adapt to another planet.

      In conclusion, i think it’s impossible to inhabit another planet but who knows, maybe the gradual increase of CO2 would give us time to adapt. I talk too much sorry😂

      • But maybe if our knowledge of biology becomes more complex, we can figure out how to adapt ourselves by using dna coding(or whatever it’s called) and make ourselves mutant. Scientists say that in a few years, we’ll be able to genetically code how we want our offspring, and maybe other animal offsprings too. Who knows what we can do with biology in a few hundred years or less?

        • Exactly! It's as pointless as worrying about alien abductions or the illiminati or whatever they're called: can't do anything about it so why worry?

          • My ex was really into conspiracy theory bullshit. I used to always just see it as annoying and kinda stupid, but now I see it as a red flag. I was in a support group session for victims/survivors of domestic violence, and I noticed something creepy. There were five of us in the meeting, and four out of five of us had an ex who was into conspiracy theory malarkey.

            I'm not saying that it's all bullshit, and perhaps there is some truth to some of it, but a lot of it is nonsense. Regardless, the fact that four out of five of us in the session had an ex who was into conspiracy theories leads me to believe that there is a certain type of pathology that many abusers tend to have in their personalities. I aware of narcissistic abusers, but perhaps there's more. I dunno, it really just struck me hard.

            I'm not saying that I'm gonna drink society's Koolaid, but I will say too much interest in conspiracy theories will be a red flag for me from here on out.

            • It would be a red flag for me because such people are delusional and I would have no respect for them. I can't imagine why there would be a link between believing in conspiracies and family violence and I've never come across it, but who knows?
