To start I believe that Aliens exist and have been visiting Earth for at least 6000 years. Not important to this discussion but that is what i believe.
I was thinking today, why tell anyone you saw a UFO or that you were abducted by aliens. I mean other than a few people who seriously research extraterrestrials, few would believe you. Even this a video of the alien abducting you, bringing you back, and saying (in alien language) 'thank you for helping with our science', and a shirt stained with alien blood as you tried to fight the effects of the parallelizing ray in the spaceship; someone on youtube will still say it is that it is made up and anyone can synthesize alien blood using gelatin, black food coloring, and human blood and no lab will certify the results because then, they think, they will be discredited and lose their jobs.
So what do you think, is it still worth the pursuit of knowledge even knowing that no one will believe you (at least for the foreseeable future)?
But here is the problem, you BELIEVE they exist so every piece of questionable "evidence" you have merely reinforces your pre-existing belief and makes you confused about why other people "just don't see it".
I would only listen to proof about extraordinary things from people who don't believe in it and have no pre-existing emotional connections to such a belief. That, or experiencing it for myself.
But I believe because I saw something that I can not explain. No I am not going into it here because I do not feel like being called a lier tonight. So by your definition of credible sources if I convinced you that UFOs visit Earth then you are no longer a credible witness or if I showed my evidence to a skeptic and they now believe then you would not believe them either, because they believe.
I'm not calling you a liar, but its very common to fill in the blanks when you don't know.
For example, a scientist is rarely sure of what he has observed but he must accept that something is the way it is because his tests have shown its the case over and over again. A single experience that you had with something you cannot explain proves nothing. And I say this as someone who once believed in ghosts for the same reason as I think you believe in aliens (though aliens are a tonne more likely than ghosts). If you showed it to the scientifically inclined skeptic, the skeptic is not likely to believe you after a single piece of evidence, but if it convinces him enough to pursue it legitimately (not as a joke Discovery Channel special) than we can say your evidence may have merit because you have convinced someone with more expertise than you to look into it.
Btw, have you heard of the new Theory as to why aliens haven't visited Earth though they probably exist? Apparently, according to new calculations and stargazing methods, Earth doesn't look like a planet with life on it. We are way too-small as compared to the Superearths that populate a lot of space with higher the size and density, and in fact we can see that Earth is not a good place for life by the many high-level extinction events that have occurred. Superearths also have an issue with a tougher atmosphere and gravity to escape from so they need to be on a much higher technological base than us to escape their worlds and begin exploring space. Just some interesting trivia
No, I had not heard that. I call it pure speculation manly because we have not yet found any 'superearths' and we have not (officially) interviewed ET to determine why. I like my pure speculation that their mission is mostly scientific.
But the 'superearth' theory is interesting.
Actually, we've found many of them.
The smallest Earth-like planet we've found is 1.9 Earth masses or higher (they can judge minimum and maximum sizes, not perfect).
http://en.wikipedia.org/wiki/Super-Earth
And here is the Theory paper:
Earth: A Borderline Planet for Life?
http://www.cfa.harvard.edu/news/2008/pr200802.html
Uh...do you read what you cite?
The term super-Earth refers only to the mass of the planet, and does not imply anything about the surface conditions or habitability. An alternative term "Gas Dwarf" may be more accurate for some examples, especially higher mass ones as suggested by MIT professor Sara Seager. Alternatively, Super-Venus or Super-Pluto might be used for super-hot or cold rocky exoplanets to give a less potentially misleading label.
That's from the wikipedia article you cited. Are you sure this has anything to do with alien life?
That's because of the method they use to find them, you can't be sure of their habitability (as planets are not bright like stars, they have to try to use the reflection from the light of stars to see the general shape of the planet).
However, it is the second link that is of more interest.
After scientists ran models, it appears that this could be the sweet-spot for habitable planets.
Also, some of those found appear to have liquid water (again according to models based on readings).
Other scientists have claimed that such a high density would inhibit plate tectonics.
Its a new thing so I'm not putting too much faith in this theory (they will have to argue this for at least 20 years before we even get close to a scientific consensus on the matter).
I mean, when we first saw the sun we thought it was a magical chariot that's flown by a god everyday in perpetuity.
I put it up there because I thought it was interesting, our earth-centric ego makes us think that alien-life must be humanoid in some way and habitable planets must be Earth-like, but it might be that our Earth is really bad at holding species. It also adds to the mystery of possible intelligent life from before humanity (for example, reading about the Homo Erectus is fascinating) that died off do to Earth's inhospitably and extinction events.
The reason I bring it up is because while I think to claim that aliens have been to Earth without us having clear proof of them is an extraordinary claim, the claim that there are no aliens in the whole of space is just as ridiculous as proven by the fact that WE are here.
As such, we must come up with theories that explain how it could be that there is alien life that has not visited Earth. This is known as the Fermi Paradox which I'm sure you know at least a little about.
http://en.wikipedia.org/wiki/Fermi_paradox
Here are the various answers:
# 5 Explaining the paradox theoretically
* 5.1 Few, if any, other civilizations currently exist
o 5.1.1 No other civilizations have arisen
o 5.1.2 It is the nature of intelligent life to destroy itself
o 5.1.3 It is the nature of intelligent life to destroy others
o 5.1.4 Life is periodically destroyed by naturally occurring events
o 5.1.5 Human beings were created alone
o 5.1.6 Metazoan lifeforms, having developed sentience, find it difficult to reproduce in micro gravity
* 5.2 They do exist, but we see no evidence
o 5.2.1 Communication is impossible due to problems of scale
+ 5.2.1.1 Intelligent civilizations are too far apart in space or time
+ 5.2.1.2 It is too expensive to spread physically throughout the galaxy
+ 5.2.1.3 Human beings have not been searching long enough
o 5.2.2 Communication is impossible for technical reasons
+ 5.2.2.1 Human beings are not listening properly
+ 5.2.2.2 Civilizations only broadcast detectable radio signals for a brief period of time
+ 5.2.2.3 The vast distances involved make detecting signals unlikely
+ 5.2.2.4 They tend to experience a technological singularity
+ 5.2.2.5 We are the first to have radio technology
o 5.2.3 They choose not to interact with us
+ 5.2.3.1 It is the nature of intelligent life to keep silent
+ 5.2.3.2 Earth is purposely isolated (The zoo hypothesis)
+ 5.2.3.3 It is dangerous to communicate
+ 5.2.3.4 They are too alien
+ 5.2.3.5 They are non-technological
o 5.2.4 They are here unobserved
These three are my favourite:
o 5.1.2 It is the nature of intelligent life to destroy itself
o 5.1.3 It is the nature of intelligent life to destroy others
o 5.1.4 Life is periodically destroyed by naturally occurring events
It would just seem odd that not a single alien species would make itself obviously known. After 6000 years(using your timeline) they know and understand us so they CAN communicate, while at the same time their technology is so much better that I doubt we can be any threat to them, while at the same time we are so primitive that we can be of no use to them whatsoever, while at the same time we are destroying our planet so if they want our resources they need to get it now.
