If they are intelligent and technologically capable then they would most likely be gregarious enough to be interested in other life forms. As we are. In fact, I think any intelligent species would go as ga-ga over microbes as we would.Sy Borg wrote: ↑October 23rd, 2023, 5:02 amI think this is right. Of all the thousands of so called "sightings" most have been explained. And the few that are as yet unexplained are likely to be explicable. They are most unlikely to be ET.value wrote: ↑October 23rd, 2023, 12:42 amScientists could also cite countless instances where humans operate with actual surgical precision.Sy Borg wrote: ↑October 22nd, 2023, 8:37 pmIt's no disgrace to be behind stone age humans, who were already extremely smart and their brains were larger than ours too. ...The orca is an apex predator and has all the peace it can ever dream of. Orcas even predate the great white shark to remove their liver. Scientists describe the event as involving 'near-surgical precision'.
Peace brings development. A tribe of nomadic hunters can never know peace and, thus, can never develop.
It's not even close. Humans pulled ahead. Far ahead. Humans are bizarre.
My issue is that intelligent creatures can be treated as if they are not, hence the cruel way of raising food mammals. Ditto the underestimation of of feeling animals, eg. cruel preparation of lobsters.
But yeah, I don't see any chance at all of biological alien life visiting Earth, and I'm dubious about any visitations per se.
The only point of travelling interstellar distances is for sheer exploration's sake, which is not a great motivation for investment, aside from the novelty/publicity value of a first launch. So it would have to be AI that has nothing better to do, and a very long time to do it. Still, there's no evidence. Some sightings are unexplained, but the chances are that there's an Earthly explanation.
That is not to say that there is not life out there, perhaps intelligent life, but we can be confident there is none in our solar system except us, and if they do exist in other systems, they are likely to be very widely dispersed and the difficulties of them getting here from other star systems are formidable. They would need a very good reason to undertake such a voyage. And maybe most will have better things to do.
So I don't think it's surprising that there is no evidence of visitation by extra-terrestrial intelligences. There is no physical evidence of them, nor any convincing evidence of electromagnetic signals from them. If they exist on the other side of our galaxy or in other galaxies, signals from them could take millions or billions of years to reach us. And the idea that ET is just dying to contact us is just anthropocentrism. No one out there cares about us. For now, there's just us and all the other species who share this little planet with us. And if we want to survive, we'd better look after the earth, our home, because no one is coming to rescue us. We have no other option. There is simply no conceivable plan B for the foreseeable future.
The issues are 1) distance a 2) motivation. What is the point in starting a colony so far from one's home world that communication over practical time spans is impossible? How could the enormous cost be justified? Perhaps only by a despotic totalitarian leader who is keen to make his, her or its mark on the universe.
I wonder if, given the challenges of exploring outer space, if advanced civilisations might find exploring inner space via digitisation of minds to be easier? It's still forbiddingly difficult, but the issues of distance in space seem completely insurmountable. However, if it becomes possible to digitise minds, then interstellar travel becomes much easier.
A tantalising thought is, if humanity becomes increasingly digital and immersed in VR, perhaps first contact could happen in that arena, if aliens decide to hack the system and say "hello" or, as the case may be, "~º†§ƒ¿"
