There are instances of groups of people who remain intentionally uncontacted, and are protected from contact with the outside world. The Inhabitants of North Sentinel Island, in the Indian Ocean are a well-known example of this. There are many uncontacted groups in tropical areas, around the world. Brazil has seven 'Terras Indigenas', areas reserved strictly for uncontacted peoples. 

If humans do this, is is so unimaginable that highly advanced civilizations could do the same with an entire inhabited planet?

Yeah even m night did it with the village

The "favorable conditions" which created the Earth was a series of extremely rare events. 

What do you base this belief on?

Facts.  Facts are a really useful tool when discussing this.  Try it out.

Our planet is an intelligence test. It gives life a certain amount of time to grow and develop and then if it doesn't get off then it kills most of the life forms and starts again. The clock is ticking...and we are going backward. Our watchers may care or we may be like life in a Petrie dish to them. 

By all means, stop the nonsense and grow up then.

Having one of the top Astronomy departments in the U.S. (Rowan University) right next to you also helps. Although I think this particular assistant from another department (me) is getting annoying. :lol:

whether life on earth is a huge series of extremely rare events or a common accurance throughout the universe is at this point just opinion and theory however, going by how vast the universe is and knowing chance,coincidence and probability i firmly have to set ego aside and give in to the notion we arent the only creatures out here and might not even be the most advanced.

However, when dealing not just with light years, forget sol travel for a moment thinking just millions of miles will we ever or has any species made a craft that can travel that far? Perhaps but thats not the only issue humans lifespan isnt that long to travel that far, why believe someother species is immortal?

Perhaps 1 light year away is a planet much like earth with creatures much like we are right now, my bet they are waxing on their UM forum is life out there and where are they, when will they get here? that answer might could be never. I know not never optimistic or fun.

So we bring in sci fi, worm holes, ships that make the jump to light speed, aliens that never die, eat, sleep or poo, so they can travel a million light years no sweat, oh. But zero proof they have been here.

If aliens are like us, there would be a lot of outlaws who don't care about laws and rules so even if we were under quarantine, there would be a lot of criminal aliens visiting us. No, I don't believe in the quarantine theory.

Available statistics would seem to indicate that life should not be uncommon but that the evolution of intelligent civilization building life is exceedingly rare.  Out of the literally billions of life forms evolved on this planet there has ever been only one species that builds civilization.  Like it or not sci-fi fans, we are rare to unique.  We are the exception not the rule.

Frank Herbert and Isaac Asimov thought the same in their later years. That's why Frank dropped the ConSentiency series and switched up to Dune and Isaac had no other technological life in the Foundation series.

Prove we are not

We dont actually know whether there is life on any of the billions of planets in the universe.

But evidence from Earth suggests that advanced tool bearing animals are very very very rare.   In the 3,500,000.000 years that life has existed on this planet, and out of many billions of lifeforms that have evolved here over that time, we have so far only found one.   Us.

Giant Moon from a just right collision (not been found)

Migrating and disintegrating gas and ice giants ( very rare in sun like systems none have been detected migrating in)

Stable magnetic field ( see giant moon) 

Just the right amount of O2 for fire ( see carbon cycle)

Just the right evolutionary pressures for meat eating mammals to start using fire. ( see "path of least resistance" and "happenchance" )

We have only just developed the telescopes and methods to spot large planets and the odd lucky transiting rock, it is impossible to say with certainty one way or the other.

Statistics however would point towards a big fat 1 for conditions being met somewhere in the universe, even the big moon you seem to be hung up on.

No we can detect their atmospheres to a certain extent and a big fat moon is needed to maintain a liquid core and plate tectonics generating a magnetic field to hold our atmosphere on and to stabilized our rotation so we don't suffer planet wide high speed winds and extreme seasonal shifts.

Seems some people are wasting their genius posting their "right" answers to all things to us low enders on a forum when they could be setting the would of astrophysics on fire with  their wealth of knowledge. ( not just in that field but all areas )

There is evidence that Jupiter may have migrated inward to its current location, not outward from the inner solar system. Disruption of the inner planets would not, in this case, appear to have been an issue. Such a scenario could apply to many solar systems.  

Earth seems to have received much of it's material from the giant collision with a Mars-sized planet, known as Theia. This collision also appears to have created the Moon. Substantial contributions to Earth's mass by any of the currently-existing planets appears very unlikely, dynamically speaking.  

Young red dwarf stars are are probably unsuitable hosts for planets with surface-dwelling life. Underground or underwater life might escape high radiation from stellar flares. These stars live an extraordinarily long time. Once they reach maturity they generally stop excessive flare activity. Thereafter they could be suitable host-stars for planets with higher forms of life on the surface. 

A  large moon is beneficial to the very long term axial stability of a planet. As we have two examples of such pairings in our own solar system-- Earth + Moon, and Pluto + Charon, it doesn't seem that these should necessarily be so very rare. 

Some planets larger than Earth, but smaller than Neptune are probably mini-Neptunes rather than super-Earths. We beginning to get a feel for where the dividing line should be drawn, though. It seems to lie somewhere between 1.6 and 2.0 times the diameter of Earth.

LOL!  Really?  Okay. 

There have been billions of species which have evolved on our planet.  Most of them are extinct.  Out of those billions there has so far been one species capable of building civilizations.  Usually evolution occurs to fill some ecological niche.  That's why for example sharks have barely changed for hundreds of millions of years.  They evolved to fill the ecological role that they are in and they've done sop perfectly.  Intelligence is not the goal of evolution, it was a shear accident.  If the earth had not been hit by a rock that killed off all of the dinosaurs our ancestors would still be mouse sized arboreal creatures that rarely touch the ground except when the next fruiting tree is too far away to climb to directly from one branch to another.  So evolutionarily speaking we are a rare accident. 

How about time and distance?  The universe is old.  billions of suns have been born and died since the big bang.  Any species evolving on planets around suns that died no longer exist.  Not even the intelligent ones.  There is a good argument that one day maybe even soon we will be extinct.  and then 10 million years later our planet is discovered and investigated by a species from another star.  They won't even know we had been here.  Or perhaps they visited while we were little single celled creatures swimming around in a primitive sea yet to evolve.  My point being that with all of that time already passed and yet to happen the chance that we and they existing at the same time and also within close enough distance to actually meet each is mathematically a slim chance.

I really could go on and on about all the reasons that there is a little chance of meeting another intelligent species but won't waste my time more right now....things to do.

Why do people care about some stupid little animal that is an endangered species on the other side of the world? We in the US spend a ton of money every year supporting various wildlife preserves all over the place. Very few of us will ever actually see one of these creatures face to face... many of them we wouldn't WANT to meet up close. Why do we waste our resources on life forms that will never have any effect on us?

 

While I can agree with some of what you said, you might be over looking one thing... We care about the "stupid little animal" because it's part of our ecosystem...We are jointly bonded together by environment... If it suffers (as a species), we all do... The same can't be said about some hypothetical alien civilization hundreds, if not tens of thousands of light years away... We are far enough apart, that we are "closed eco-systems" at least in relation to each other...

Other than curiousity (which we do not know another species would have to any great degree), a desire to exploit us for our resources or a desire to colonize our system (either in a friendly or non-friendly manner), there are few other reasons to go to another system. The distances and time to travel are too great to make it practical for any other reasons - unless the alien civilization is the proud possessor of some super sci-fi ability to travel greatly over the speed of light for no cost whatsoever...

Either they are equal to or below us technologically and can't detect us, or they are too far away and haven't had the time to find us, they just don't care or they don't exist...

Most sun like stars are surrounded by gas and ice giants. Ours isn't because Jupiter's migration cleared most of them them out and Mercury was close enough to the sun to be stripped of all it's layers. Thus allowing the Earth to form

The " goldilocks zone"  around red dwarfs is a solar flare and radiation death trap.

Then you need a big enough moon to stabilize the planet's rotation and create internal "tides" allowing a magnetic field to be maintained. 

'Super Earths" are really "mini-Neptunes". The atmosphere would be too thick for fire or bi-pedalism.  Thus no technology. 

The thing is that you are working on the assumption that all intelligent life has to look and be based on an evolutionary path almost exactly like ours. Since we only have the one system to study it makes it hard to imagine but there are quite possibly other ways and forms that life can arise and become intelligent.  We just don't know and don't have enough information to have any set in stone for sure answers to most of the questions about life on other planets. Open your mind and let your imagination run. The worst that can happen is that you will be wrong and that means less than you can imagine. Better to have imagined and been wrong than refuse to consider the odd and be thoughtless.

Absolutely.  But the way to really judge is to go by what we know as proven fact.  You're talking fantasy not based on any fact that we know of.

Sorry...face it...facts indisputable prove it, humans are the only creatures in the vast universe of of intelligence with ability to building civilizations, while its a bit boring and makes me feel a bit alone i understand that whats more important is it makes some feel so much more special and epic they need that and have the proof we are it.

I think i should by george a drink.

One of Frank Herbert's possible theories was a planet wide plant-animal and although it didn't develop technology. It developed sentience.
