Believing in Nothing is still believing in Something.I'd rather believe there is nothing than I would believe in something that nobody has ever seen (not just with eyes, with any sense or machinery). Do you think this way about fairies? How about dragons? Giant sand worms?
I try to hold no belief on any topic... just shades of probability and levels of usefulness.
Accepting an old Jewish book and its metaphysics, of which we have no supporting evidence, appears to me as not very useful and having a very low probability of being True.
Accepting that we have figured out how the Universe came into existence and how everything works, may be useful when examining some things, but I don't have enough faith in humans to think it highly probable that we've seen nearly enough evidence to come to any conclusions.
Fairies, Dragons, Unicorns etc... I stick in the "Unknown" category. I have seen no evidence that supports their existence, but I don't presume that I've seen all the evidence that may exist.
I'm not sure why so many people feel it necessary to conclude with belief or non-belief when they can just say "maybe" or "I don't know"...
