That would be research from a hypothesis. A more common research is to observe something and try to figure why it is so.

Again, too deep.

If someone says something without evidence, you can dismiss it without evidence too. Just because you can't prove something is wrong doesn't mean it is right till you prove otherwise.

If that were the case, the corrupt logic of religion would be valid. Saying a religious text is true defeats the object of faith unless I am mistaken?
