1. So how did belief enter science?
2. How did scientists get to that belief?
It did not, that was my point.
Science have not investigate santa or the flying spaghettimonster either, to my knowledge at least.
Science is not a entity that can hold a belief... It is a system we use to investigate the world, it has no beliefs.
What I meant was that; maybe the reason for this is that most PEOPLE don't believe in them...
And this conversation is again derailing, it is not about fairies. It is about; lack of evidence does not prove non existence.
So lets forget about the fairies and get back on topic.
One of the examples in the link I gave is that which the discussion started with. It should prove to you that you are incorrect in your understanding:
I. Argumentum ad Ignorantiam: (appeal to ignorance) the fallacy that a proposition is true simply on the basis that it has not been proved false or that it is false simply because it has not been proved true. This error in reasoning is often expressed with influential rhetoric.
A. The informal structure has two basic patterns: Statement p is unproved.
Not-p is true.Statement not-p is unproved.
p is true.B. If one argues that God or telepathy, ghosts, or UFO's do not exist because their existence has not been proven beyond a shadow of doubt, then this fallacy occurs.
I know you don't like Wikipedia, but since you apparently prefer to use Wikipedia's reference I thought I use it anyway:

A false dilemma may take the form:
- If a proposition has not been disproven, then it cannot be considered false and must therefore be considered true.
- If a proposition has not been proven, then it cannot be considered true and must therefore be considered false.
- "There is no evidence of aliens, and therefore, aliens do not exist" appeals to an absence of evidence

There are plenty of examples of this fallacy, both on Wikipedia and it's sources.
