Why claims of extraterrestrials visiting Earth are unfounded.
(1) Radar blips, blurry night lights in the sky, and back water swamp abductions are not credible evidence of extraterrestrials. It’s not scientific evidence, and wouldn’t even be evidence in a court of law. At best it’s circumstantial evidence.
(2) What would irrefutable evidence look like? Extraterrestrials landing in plain view, in broad daylight in front of hundreds or millions of people. Then went on a Beatles like world tour, so we can exclude the possibility of a brilliant hoax by any one group of people, or government.
(3) The stories from eye witnesses and abductees lack any logic. If aliens don’t want to be seen, why are they experimenting on conscious victims? Where’s the evidence victims have been experimented on?
(4) The behavior of extraterrestrials are illogical. If aliens don’t want to be seen, why are they so bad at hiding? (That’s if you consider radar blips and lights in the sky evidence of aliens.) Why the secret abductions? If they’re so far advanced they could either go completely undetected, or make an obvious attempt at making contact.
(5) Governments keeping extraterrestrials a secret from the public are illogical. Governments are pretty bad at keeping secrets to begin with. Second, millions of government employees and scientists around the world would have to be in on the secret. Why are governments and scientists spending billions on rudimentary space exploration for past or present life, if they already have the evidence of advanced extraterrestrial life forms?
(6) The universe is a sterile place. The solar winds wipes away protective atmospheres and the radiation can kill anything in space or above ground. (Down to a few meters I believe) And it’s not just stars that emit deadly radiation. If an unprotected human being flew anywhere near Jupiter, they would be killed instantly by the deadly energetic particles it traps from the solar winds.
(7) Evolution is dictated by the circumstances of the environment. What the planet is made of, it’s size, gravity, atmosphere, orbit around it’s star, moons, local competing life forms, climate, disease, and natural disasters. The chances alien life elsewhere would evolve into a humanoid species that pretty much mirrors the evolutionary path of homo sapiens is very unlikely.
(8) What were the many chance circumstances needed for life to prosper as we know it on Earth? (leading to intelligent life)
a) The Earth had to be big enough so it had enough gravity to hold an atmosphere.
b) It must orbit the Sun in just the right habitual zone so there could be liquid water. (No liquid water, no life.)
c) A large size moon stabilizes the rotation of the Earth. Without the Moon our climate would be far more unstable, and ever changing, which would have made the possibility of life taking root and evolving unlikely.
d) Our planet needed a magnetic field to protects the Earth and it’s atmosphere from the solar winds. Without a magnetic field, we would be a dry dead planet. (no other rocky planets or moons in our solar system have a magnetic field. Well, I think Venus has one but it has more to do with the Sun than the planet itself, kinda like Jupiter)
e) Human life wouldn’t have evolved without chance and circumstance. Dinosaurs ruled the Earth for 165 million years. Without their sudden extinction, mammals couldn’t prosper and evolved from the tiny borrowing creatures they were.
f) How did humans become intelligent? By chance. Humans learned to master fire and began to cook their meat. This process gave us more protein which made our brains grow. Without cooking our meat we would likely be as intelligent as a modern day mammal, a lion or dog.
(9) We have no idea what created the “spark of life” on Earth. We know the ingredients of life, and we know the conditions needed for life as we know it. But without knowing what created life in the first place, there’s no mathematical equation which can theorize the possibility of life in the universe. Right now the instance of life is “one”. You can have a billion Earth like planets but until you know the likelihood of life instantaneously spawning elsewhere it’s zero.
In conclusion, I’m not as closed minded as some think. If we found microbial life (or fossils) somewhere else in our solar system that would change everything. Especially if we could prove this other instance of life was completely unique onto itself. In other words life didn’t come to Earth from somewhere else, or vice versa. Still it’s a long stretch to go from simple life forms to intelligent life. Until then, it’s nothing more than fodder of the imagination, and fun to speculate.

It's funny y'know.
There's never been any evidence. Everybody knows there's never been any evidence.
Which of course has no bearing on whether it might or might not have happened. And the statistics can never be evaluated either, because no-one knows the size of the universe. The larger, the more possible.

@ Solium, I agree the "evidence" for extraterrestrial or extrasolar visitors is sketchy, at best. I have not made an in-depth study of the claims. The fact that so many stories are obvious or proven hoaxes understandably discourages anyone inclined to make a serious study.
Mercury has a magnetosphere, while Venus has a plasma "double layer," as described by Irving Langmuir. (Venus's magnetotail reaches all the way to the orbit of Earth.) Titan has a surface acceleration far lower than that of Earth, yet has a denser atmosphere. Venus has a surface acceleration slightly lower than Earth's, yet an atmosphere far denser than Earth's. Gravity alone cannot explain these variances—that is, assuming everything in the Solar system was created at the same time, as required by the nebular hypothesis. Thus, it is possible that some of the celestial bodies are younger. And there are other potential factors.

There is plenty of solid evidence UFOs exist...nothing verifying their origin, however.

Solium wrote: I should have said a substantial atmosphere. Of course Mars has an atmosphere, and technically so does Pluto. But neither can sustain life as we know it on the surface.
If you want to make that case, the Moon has an "atmosphere" too, and many planetoids develop a coma, thus blurring the line between planetoids and comets. I was simply pointing out the disconnect between higher gravity and denser atmosphere. The established origin and evolution of life on Earth seems sound enough. But outside high school textbooks, the model becomes much more tenuous.
Tardigrades are one example of an incredibly robust "macro" animal that can survive amazing extremes of temperature, ionizing radiation, hard vacuum and decades of dormancy. They cannot subsist in a vacuum, and doubtless originated in a much more clement environment. But they show that it might be possible for an entire planetary system to have a common form of life.
Suppose more than one body in a planetary system developed life, and the two or more types managed to end up in the same environment. (Remember ALH84001.) Biologists might come up with some pretty convoluted models to explain the variations, perhaps learning only much later that life is a hybrid from more than one place.

Space & Stars was known well over 400 years ago, by an English astronomer, Thomas Digges, he was the first to solve the theory about Stars, what there about, & a number of other things.
400 year later, hundred's more astronomers, countless space missions, & trillions of money spent, & still no organisms, life.
All that history in space is fabrication, a number of body's have been found over the years, (Aliens) on earth, they've all turned out to bee fakes, ditto with the pictures too, misleading yap means nothing without facts.
Them capsules flying around, there not (Martians) no chance, there government issue, over there at area 51 strange things go on. & a few other countries.
There's only animals & human's in this entire universe, all other beliefs are negative, the main concern is mother nature, & human nuclear war's worldwide, Martians, Mutants, Aliens don't exist, just little ET & CO.

I can well believe that no denizens of other worlds have ever visited ours. I did happen to see a UFO once, but of course the mere fact of its being unidentifiable does not necessarily indicate the nature or origin of its passengers, or even if there were any. FWIW, there is one school of thought among certain UFOlogists which posits the theory that UFO's are not extraterrestrial but inter-dimensional. I seem to have read somewhere that a regard for this theory is one reason why the Mother Ship in CLOSE ENCOUNTERS is first seen rising up from behind the mountain, not descending down toward it.

Would be awe inspiring if there were extraterrestrial spaceships that visited us from the depths of outer space, but just because it would be great does not mean it is true, and one should not believe something just because it would be neat. There is no real evidence, much less proof, that any extra terrestrial life form has ever visited us from planets in outer space.
