I believe it is better not to believe than to believe something that is as likely as not a lie. What little I do believe, I cherish, not because I wish or hope that it's true, but because it has passed the test of scrutiny and avails itself to understanding through a process of reason, a process that should never be subject to nor denied on behalf of a cherished belief.
The value of knowledge can only be measured with respect to our understanding by which we take possession of and become its stewards and rightful heirs with the capacity to pass it on to others for whom understanding is likewise the gold standard by which the value of believing should be measured.
Knowing where we came from and how we got here is only important to the point that it informs us of who and what we are and of what possibilities are available to us and which choices will maximise the value of the all too brief and no less precious moment the universe has bestowed upon us to appreciate and enjoy our time under the Sun.
Whether or not what I believe strikes a chord with you, it is in no wise as important to me as your understanding of why I believe it. But based on previous experience, a detailed mutual discussion of that is in all likelihood by now, out of the question.
