There is much that can be said about this.
For example, i see many similarities between those who see a blinking dot in the sky and state that it IS an alien spacecraft and those who see the
Virgin Mary on rocks, Trees and clouds: it's more or less the same form of Hysteria.
And in the other side, there are those who state that it was a plane, no wait: venus. no, wait: riegel. No wait: it was anything but an alien
spacecraft because it could NOT be one: those fall into the same basket, because that's another form of being blind: blind accepting VS. blind
The differences between the two is that while the first ones are pushed by some enthusiastic will to believe, the second ones are pushed by FEAR: fear
for the unkown, fear to look foolish, fear to don't look cool enough: they will always tell you that the reason is absence of proofs, but that's not
Regarding these two groups, i sypathize with the first one, without doubts: but neither the first nor the second have many chances to contribute in
moving some serious steps towards the truth.
Another, completely different scenario, is the one in which you have:
those who learn about something that has been witnessed, or documented, or tracked by radars, or covered by media or all this stuff alltogether, and
which general features were NOT consistent with anything mundane, or celestial body etc. and state that it's an interesting sighting, and that some
alien spacecraft cannot be ruled out.
Those are believers as well, but they want to touch the truth with their own hands: it is THIS type of believers that we need, because they add anyway
to the research, no matter if this or that case turns out to be some misinterpretation, or some hoax AFTER serious investigations.
In the other side, we have those who, after looking at a footage, reading its description, reading the related reports say: "in my opinion it was a
plane because i see clearly a red, a white and a green light, its motion is regular and everything is consistent with a plane". That would be a
serious opinion, and those are the type of skeptics that we need as well, no matter if his opinion turns out to be wrong: it's the CONSTRUCTION that
After the above four, there would be many categories more, but what i'd like to say is that CURIOSITY is the keyword: be curious and you will be
pushed to find out more. And in order to find out more you must to research: and in order to research you must study and after studing you wil get
more trained and more able to distinguish between a joke and some serious UFO case: and when somone looks at you down upon, stop him and ask him the
why. Maybe he will walk away without saying a word, but maybe he will tell you something in some fair way, about your behavior, or about your approach
to the subject matter, or just about the way you express your beliefs; and maybe what he will say will be helpful to you, and will force you to
Thanks for the nice OP and for some GREAT contributions
