I know that there are times when a person asks for more information, it is because what little information the OP has given requires it. There are times when a story sounds intriguing and more details are needed. It isn't always about believing the story in its entirety right away. If someone posts, "I saw a UFO last night" and the next poster writes, "show us a picture." it isn't because the second poster believes, it is because she or he wants to see proof.
Certainly there are people here and everywhere that believe everything they are told, but I don't believe them to be the majority.
And from what I've seen it takes some people more than once post from the OP in order for them to make up their minds about whether they believe or not. That is healthier than determining if the story is true or false right away, in my opinion.
Answer me this, please: if you have never been to China (or pick a country) can you prove it exists? Oh sure, there are pictures and people who claim to have been there. Heck there are even people who claim to live there *gasp*. But all of that can be said for aliens and spaceships, too. So can you prove there is a China without stepping foot on its soil, without seeing it for your own eyes?
There is nothing wrong with believing and there is nothing wrong with being skeptical. I aim for right down the middle, but that is just me
