UFOs

[Bill]

This phenomena has been happening for as long as there have been people. We keep experiencing it differently depending on our personal and societal beliefs.

o,
then , now big parabolic shot :
last research of dying humans showing brains mas production of the DMT, psychoactive alkaloid found in the Banisteria Capi used by Amazonian tribes for spiritual connections.
Legends go, that knowledge of the plants was given by multidimensional ET.
So
Question is : do we transmigrating , or hallucinating while de- compositing ?

Sorry, I don't know if we covered the Great Filter already. Given the Fermi Paradox (there should theoretically be intelligent life, yet despite searching really hard, we cannot find any evidence whatsover), the Great Filter hypothesis ponders what might be happening and that certain steps (out of 9) may be very unlikely. It doesn't seem to cover the criticism of the Fermi Paradox that we aren't "listening" correctly.

With no evidence of intelligent life other than ourselves, it appears that the process of starting with a star and ending with "advanced explosive lasting life" must be unlikely. This implies that at least one step in this process must be improbable. Hanson's list, while incomplete, describes the following nine steps in an "evolutionary path" that results in the colonization of the observable universe:

1. The right star system (including organics and potentially habitable planets)
2. Reproductive molecules (e.g., RNA)
3. Simple (prokaryotic) single-cell life
4. Complex (eukaryotic) single-cell life
5. Sexual reproduction
6. Multi-cell life
7. Tool-using animals with big brains
8. Where we are now
9. Colonization explosion.
According to the Great Filter hypothesis at least one of these steps—if the list were complete—must be improbable. If it's not an early step (i.e., in our past), then the implication is that the improbable step lies in our future and our prospects of reaching step 9 (interstellar colonization) are still bleak. If the past steps are likely, then many civilizations would have developed to the current level of the human species. However, none appear to have made it to step 9, or the Milky Way would be full of colonies. So perhaps step 9 is the unlikely one, and the only thing that appears likely to keep us from step 9 is some sort of catastrophe or resource exhaustion leading to the impossibility of making the step due to consumption of the available resources (like for example highly constrained energy resources).[7] So by this argument, finding multicellular life on Mars (provided it evolved independently) would be bad news, since it would imply steps 2–6 are easy, and hence only 1, 7, 8 or 9 (or some unknown step) could be the big problem.[4]

There is a Rare Earth hypothesis. https://en.wikipedia.org/wiki/Rare_Earth_hypothesis

too long an argument and set of counter arguments to post but here is one interesting tidbit - we are likely the most advanced life even if there are other earth-like planets

Ray Kurzweil, a computer pioneer and self-proclaimed Singularitarian, argues in The Singularity Is Near that the coming Singularity requires that Earth be the first planet on which sentient, technology-using life evolved. Although other Earth-like planets could exist, Earth must be the most evolutionarily advanced, because otherwise we would have seen evidence that another culture had experienced the Singularity and expanded to harness the full computational capacity of the physical universe.

[Steve James]

I don't know if it's necessary that the Earth be the first planet on which sentient, technology using life evolved. There could be civilizations that just haven't gotten to the point of using electricity. Our civilization (ie., sentient technological humans) has only had the capability for 200 years --at very best. If there were a Roman-like civilization 50+ light years, we might easily miss them; and they would have not have reached the point where they could receive or transmit messages that far.

We're the first that we've found, but we've only been looking into space for a short time. Sure, people have argued that there were beings in clouds, or riding the sun, or in divine chariots. But, it wasn't until very recently in human history, and nothing at all in terms of biological history on the Earth, that we've considered there were people living on other planets who could use vehicles to reach us. I.e., ancient humans did not think they could get to the moon using a wheel. Rockets to the moon were conceived after rockets were invented.

Anyway, it took 3 billion years for life to develop to this point. I'd argue that anywhere we would find sentient technological civilizations, we'd also find less sentient non-technological living things. I don't think humans could exist, for ex., without a lot of other living things. The preference of human primates for meat, as opposed to the primarily vegetarian diets of other higher primates, probably led to many other changes --including brain development.

If there were aliens with electric lighting, or planets needing lighting, we'd probably see them, assuming that they live on the surface. A thousand years ago, how would anyone know about us? Anyway, if nothing is inevitable, then we might also be the last.

..."Anyway, it took 3 billion years for life to develop to this point..."
so
If we compare it to the age of the universe our life form is quite young, and in the fact we just scratch the box with knowledge

..."Rockets to the moon were conceived after rockets were invented..."
Steve, what with the Palenque Maya`s tomb image,then, where guy is sitting inside one?, for example.

@Trick
I`m not so sure, `cause behind the light you` will met someone 1st, and you may get kick back

[Trick]

A thousand years ago earth might be what similar developed spices on a thousand light years away planet is seeing trough their telescopes. They might think-‘wow a planet in the habitable zone’. No matter how far away, as long as they can se or just suspect this planet could be a possible (near)match to their own they probably want to find out more about it....They might already be on their way.....The UFO’s are just their reconnaissance drones.

[Trick]

Electricity as mentioned in the thread, it’s practical usage has been around some 200 years, quite a short time. But we have made huge technical advancements in that short time, if we continue this rapid advancement for another millennia or two, where will we be then...blown ourself back to stone age or blown the minds of the ET’s by our tremendous technical achievements in such a “short time”.........Electricity usage might have had some sparks in ancient times but seemingly did not spark a huge interest or maybe where suppressed. https://en.wikipedia.org/wiki/Coso_artifact https://en.wikipedia.org/wiki/Dendera_light https://en.wikipedia.org/wiki/Baghdad_Battery

[wiesiek]

yup,
compare to the cosmos evolution time,
we don`t know even our own shit to much...

[Steve James]

Well, as I suggested, if we got to Mars, we wouldn't build in stone. Even the Romans had concrete. And it's just unlikely that aliens would survive here or on Mars without life support. So, at this point, I don't accept Mayan or any ruins as evidence of aliens. Aliens more advanced than modern humans would construct things far more advanced than ours, even a thousand years ago.

Oh, anything that looks like a typical rocket is impractical or unnecessary for interstellar travel. Saucers are the same. They're the products of human imagination. There's no need for aerodynamics in space, and saucers are physically silly.

Afa electrity, obviously the aliens didn't use wires. That would be primitive technology.

[Trick]

Cylindric or saucer(disk) space ships/stations if rotating the right way could imitate gravity?

[Steve James]

A square or triangle could also be rotated to imitate gravity, too. And, is there a reason to believe that aliens would need to recreate gravity at all. Clearly, we've managed to travel in space without that ability.

[Trick]

The roundness might make it for a smother roundabout walk in the ship ?

[Trick]

Clearly, we've managed to travel in space without that ability.

yes but if we need to be in space for a really long time one with lose ones Taijiquan skill without any gravity
