I'm not too worried about belief, given that I can believe anything and it amounts to nothing. I prefer to stick with the facts, but when that is not possible, such as with understanding the reason for all being, I simply consider a myriad of possibilities and hope it might that which is most beneficial.
To me, creation without cause is rather liberating because it means that life has no other purpose than what I choose to assign it. Although I could allow it to mean nothing, I figure it must be more enjoyable to have it mean something which I care about.
