What is God?

[BrianSoddingBoru4]

if you choose to disbelieve it,you are doing the same thing,i.e,you are disbelieving in something without evidence to support your action,which is equally irrational.

Not at all.  Opting to disbelieve in things for which there is no evidence (or very poor evidence) is perfectly rational.

I'm eight feet tall, have six arms, and my skin is a delightful shade of dark purple.  You can't see this, because I also have the psionic ability to cause people to see me as 6'4" tall with two arms and pale skin.  You have no evidence that any of this is true, and thus no reason to believe it.  By default, it is rational of you to disbelieve it.
