Will humans exist forever?

Answer 1

no. the more complex an organism, the easier they go extinct.

trilobites lasted around 300 million years; a not-so-complex animal.

dinosaurs lasted about 150 million years; more complex, shorter reign.

humans, we haven't even come CLOSE to how long dinosaurs we around, we'll go extinct soon enough.

Answer 2

No. Either we will evolve into something else or we'll find a way to end our existence.

The earth is over 4 billion years old and life here has existed for about 3 billion years. Species like the termite and ant have already been around for hundreds of millions of years, while humans have only been around for a hundred thousand years or so. In the total scheme of life on earth, it hasn't even been decided yet if we are a successful species.

Answer 3

Define forever...
Here is how I see it; on this planet many species have come and many species have gone. They become extinct because something happened such as a natural disaster that wiped out food supply or perhaps even changed environmental conditions such as temperature, another species or mutation of their species was better suited to survive and competed with them for food (and won), or their population just gets too large and they exhaust their resources and then undergo massive die-off when the resources run out.

What I forsee happening is for the human population to get so large that we exhaust all of out resources -ie: there is not enough food to go around, not enough energy resources, not enough clean water. Being at the top of the food chain is tough because nothing is there to keep our population in check. So we will coninue to grow and grow and use up all of earths resources until the point that we just exhaust them. At that point we will undergo massive die-offs as people die from hunger, thirst, and diseases. I'm not saying humans will go completely extinct, there will more than likely still be a small population left to carry on.

As far as existing "forever", earth is constantly changing, its been changing for millions of years, the planet has warmed up, the continents shift, and species are constantly evolving to be better suited to live on this planet. Change for the most part is gradual, however change can also be very quick. Such as the meteor that struck earth kicking up a layer of dust and ash that blocked out the sun and wiped out the food supply for the dinosaurs, they all died out because they could not handle that much change at once. You just simply never know when another large scale natural disaster may occur.

That is the best answer I have, depending if in your question you were talking about the physical presence of the human species on earth. This could also be a question of spirituality. I do not know your beliefs but if you believe that your soul will continue to live after death, then yes humans will "live forever".

Hope this helps.

Answer 4

Nothing is destined to exist forever in this world. The human beings are also destined to perish some day or may take the shape of some different creature on this earth.

Take the example of dinosaurs, they existed some millions of years early but they are not existing presently on earth. Likewise all depends on the changes on earth and other neighbouring planets, as well as the evolution of the mankind.

Answer 5

If one believes in a supreme being then yes Humans will be in existence forever. From a "scientific" side the human race is just in trouble as the odds of a catastrophe destroying this planet far out weigh are ability to survive or colonize other planets soon enough.

Answer 6

No, humans will not exist forever.

First, it seems highly likely that we will destroy ourselves (Martin Rees gives us a 50 / 50 chance of surviving this century alone... if you're reading this in the 22nd century we got lucky!)

Putting aside all questions of us destroying ourselves or catastrophic impacts from meteors, it seems unlikely that we will exist in millions of years time.

This is simply due to evolution - we know from looking at the past that living entities evolve and change over time. Therefore since we are part of the process, surely we too will evolve.

Hence there may be creatures like humans around in a few million years time, but for the current species homo sapiens to still exist seems surely unlikely. Certainly by the time the sun turns red and starts helium fusion, we will be long gone.

Answer 7

Humans will not exist forever, because I read in a book that in 3000 years more the sun will explode, so if there's no sun there's no energy.

Another explanation is Ozone depletion, if we don't stop using chemicals the ozone will deplete and we will not have protection from UV
rays.

Where will we live in 10 more years? the Earth is becoming more crowded each year.

Global Warming- Scientists are saying that we will face global warming, the Earth will become warmer and it will be harder for us to survive.

**I don't know if this answers are accurate but that's what my biology teacher told me, and in my opinion I don't think humans will exist forever

Answer 8

Yes they will. We were not put here to simply exist for awhile then go extinct. Not everyone will make it but the human race will survive forever.

Answer 9

Hopefully not. Humans should have made themselves extinct hundreds of years ago. We are overdue to dying out as a species. We deserve that much by treating this planet like a toilet......

Answer 10

No.

1. At least in the short term (hundreds of years), we will remain capable of destroying ourselves as a species through nuclear war. I consider that far less likely than a nuclear exchange which *merely* kills hundreds of millions.

2. We will remain vulnerable to disease pandemics for the foreseeable future. I doubt that an emerging disease could wipe out the majority of humanity, much less anihilate us altogether.

3. On longer time-scales, the gobal effects of a massive caldera eruption (Yellowstone, Toba, etc.) could drasticly reduce human populations to the point where disease could finish us off. Climatic effects could rule out large-scale agriculture for several years - leading to starvation and chaos.

4. On time scales of millions of years we would face devastation from impacting asteroids and comets. A 10km-wide asteroid would certainly threaten our survival, promptly killing a large fraction of the human population within hours of impact. The rest would suffer tremendous stress due to starvation, complete destruction of infrastructure on a worldwide scale, etc. A comet of similar size could certainly cause as much or more havoc, due to the truly extraordinary impact speeds made possible by their orbits.

5. I can't think of a reason why natural selection in our species would necessarily favor the level of intelligence exhibited by modern day humans. In the absence of stresses requiring more intelligence to surmount, selection would seem to favor those most willing and able to procreate and feed themselves. Who knows? But the question remains whether we would identify our descendants 100,000 generations from now as *human*.

6. The LONG term...Our descendants, in whatever form they might survive in, if they survive at all, will at some point find themselves occupying a dying planet. It could be a few hundred million years from now or a few billion. In either case, the sun will begin to slowly expand at some point - heating the planet to a point where vegetation cannot survive, evaporating the oceans and eventually driving off the atmosphere and any remaining volatile substances. If we have not developed independent populations at distances sufficient to avoid lethal effects from the dying star, we're toast...plain and simple.

7. The LOOONG term: Suppose we develop a way to reach other solar systems and colonize them (in principle, this could be done over many generations with propulsion techniques well beyond our current capabilities)...Well, the same issues will arise on any given planet in any star system. Stars die. As the galaxy ages, fewer and fewer new stars will form.

The matter we observe in the universe can support stars for a large (but very finite) amount of time. How long, in a darkening universe, perpetually seeking energy to sustain itself, could a species survive?

Nothing lasts forever.

Enjoy life. Take a walk. Look at the flowers. Love someone.

Answer 11

Nothing will survive... Eventually there will be some sort of galactic disaster that humans will not be able to escape from, no matter how far out into space we will go.

Make no mistake... the universe does not care.
