In the past 60,000 years no other species has had anywhere near as much success as humans have. It wasn't because we were good at running (although that helped). With fire and shelter we can survive in almost any conditions. Link to comment Share on other sites More sharing options...

How long have roaches, rats, ants, tardigrades, fungi, and bacteria been around? How widespread are they? The more complex and specialized members of a society become the more fragile the structure. Not so bad when everybody can make the three needed flint survival tools to hunt and gather.

That would put our population back down to what it was in the early 18th century, but it should come back a lot faster the second time since we'll still have most of the knowledge we had before.

Well, an outside observer might say that was because Antarctica is the only place humans have not been out competed by other species. 6 minutes ago, astrobeing said: So that would leave 700 million humans to repopulate the planet after the next extinction event.

Anyone who wants to wipe humans out is going to have a hard time! First convince them that infectious diseases are no big deal. Then let them forget how important bees are to crop pollination. You might find this book interesting, It reviews historical examples of societies that failed or went extinct. I took us far afield. As for the OP, I tend to agree that intelligent life is rare. I don't think intelligence is as much of a bulwark against extinction as some do. Link to comment Share on other sites More sharing options...

I've read it. It shows what happens when humans are confined to small areas which humans as a species aren't fortunately. I've found that people who think humans are doomed as a species are the ones doing most to doom them. Fortunately they're a minority so I don't think intelligent species are automatically doomed.

Well neither do I, nor is survival assured. We just play the game and try to do it smartly. Though for the moment, we are confined to a small space, the Earth. 2 Link to comment Share on other sites More sharing options...

No. I have been killing fireants on my property for 13 years. Cannot annihilate them. Long after humans are extinct, the fire ants will still be here...along with the weeds. I think if a planet has any life...sooner or later that life will evolve into beings with intelligence. There are trillions of galaxies, each having billions of star systems. But even if there was intelligent life on our closest star we would never know it. Intelligence doesn't necessarily mean the ability to send out or receive radio waves. 4 Link to comment Share on other sites More sharing options...

glorybebe Posted December 6, 2020 #43 Share Posted December 6, 2020 9 hours ago, astrobeing said: They are not assumptions. They are conclusions based on two hundred years of analysis of evidence collected on Earth. Nothing in this evidence remotely suggests that the emergence and evolution of life on our planet was influenced by any intelligence therefore that theory has certainly been proven wrong. Science works with evidence, not unfounded speculation. And this is where I agree with Papa. All the 'evidence' is based on Earth. Do all planets have to have the exact same conditions as Earth to produce life? There are so many variables out there that could produce intelligent life, but we can't base everything on what happened here on Earth. That is just small minded IMO. 3 Link to comment Share on other sites More sharing options...

So you're saying that since we don't have any extraterrestrial evidence that we should just make extraterrestrial evidence up from our imaginations? As I said twice so far this is called "speculation" and that should never be confused with actual evidence. Remember we're discussing a scientific study, not people's opinions. Tell me more about these "many variables out there that could produce intelligent life". I studied a lot of chemistry and organic chemistry in college but I've never come across these "variables".

I have come across them in science fiction. No, I am not saying make stuff up! Where did you get that. What I am saying is that we cannot base every planet on Earth. Look at the different planets in our solar system. Look at astronomers thinking life could be in Venus's atmosphere. How different is Venus's atmosphere from Earth. Even with the possibility dwindling that life could be supported there, how did astronomers get the idea? Not every planet will be the same. Not every planet will have the exact same conditions as Earth. The whole point us we do not know. Trying to put all other planets into the exact same conditions as Earth is making assumptions that life can only start if the planets is exactly like Earth. They cannot say that without out proof. 1 Link to comment Share on other sites More sharing options...

I'm kind of having a problem with that. I have heard of theories of, for instance, Silicone based life forms. Mmmmm...no. We have to begin with the assumption that all life must be carbon based because all life is carbon based. In fact...all life that we know of is on Earth. Then there are arguments to what really constitutes life. Is a hunk of chicken muscle grown in a lab life? Is some microbial something in the atmosphere of Venus life? I just have to fall back to the physics of it all. There are trillions of galaxies. But we know that every single galaxy...every single star system...all of it is within the realm of our own understanding of physics. Otherwise we wouldn't know all we know about the Universe. Physics doesn't change because some planets are in galaxies a million light years away. but as @Tatetopa correctly mused...the word rare is a bit ambiguous. The thinking is that the odds are great that life exists on other planets. But the thinking that it is a rare thing isn't really new. It has to be rare. Because as far as we actually know. We are it. And...we do know more or less how life began on this planet. So, it is within the realm of scientific thought that the same circumstances might happen somewhere else. But since there is no other life in the universe that we know of, we do kind of have to go with the thought that carbon based life forms are the only life forms. 4 Link to comment Share on other sites More sharing options...
