If I'm going way off topic please feel free to ignore this post: but this is an interesting point.
Belief in an external world is just that - a belief, by virtue of the fact that we can never amass evidence for its existence (sorry to bring this up greedoniz

). Yet this is not something we
choose to believe when we grow up (generally speaking of course, I'm sure there are some exceptions) but something we merely accept as a given.
So to say that a belief is something we can choose freely is not quite accurate. Taking a Determinist approach, it could be argued that we do not have a truly free free will; what we choose to believe (not to mention every action we ever make) is influenced by the world around us (if it even exists at all!).

None of these pondering changes any of the original question on why some people insist on denying or ignoring the extremely reliable information that science brings us and instead believe in the more fantastical.
Greedoniz, you are correct in saying that the questions raised by Philosophy do not
fully answer your original question, but they are important in making apparent just how much we can trust what our senses tell us, and thus the conclusions they lead us to make about the world as well as showing the importance of clarifying the terms involved.
For instance: you say that the rational mind should embrace empirical evidence; but (to use Descartes to illustrate once again) Rationalists reject empirical evidence on the grounds that it cannot be entirely trusted - quite a rational argument indeed!
Descartes reasoned rationally that God existed, yet you claim that the rational mind is one which only accepts something if and only if there is evidence for its existence...
Using my rational mind however

I do not believe that there could ever be any proof for the existence of a God - Religion is based on faith after all. The Bible (if I'm not mistaken) mentions that only those who
believe in God (different from KNOWing of his existence) will be allowed entry to Heaven - and what better way to distinguish between the believers and the non-believers than making it so that no evidence could ever be found to prove the existence of You (God). But then there are theological problems such as The Euthyphro Dilemma and The Problem of Evil which are quite rational and seem to undermine the existence of a God - thus I am forced to adpot an Agnostic approach.
I hope that makes some sense at least... it's very hot after all.
