For an atheist (or agnostic), is the word "sacred" meaningful? Do you have a sense of the sacred?
If so, in what way? What counts to you as sacred?
What counts as not sacred?
Life is sacred, extremely so. Human life most, because I'm human. That's about it for me.
Great creations of humanity are by-association sacred to me. I would never burn a book, deface a work of art, so forth and so on. These things evoke a great sense of sacredness in me, but it's not quite on the same level as life, so I'm not sure (does "sacred" only apply to the maximum, or are there various levels of sacred? I guess that's more of a linguistics question!).
EDIT: Ok, I figured out what the most sacred thing to me is as far as how it makes me feel. A big oooolllllld tree. I repect things that are better evolved for their niche than I am, and like sharks and bees, trees are pretty perfect for what they do. Also, they live a lot longer than me, and the older something is the more awed by it I am.
I could sit next to a really ancient tree all day feeling humbled.
From my stance I would say you are partially right and partially wrong.
I understand from the aspect of an atheist saying that "no deity" is the default. I understand the frustration in it being argued otherwise too. I will go on to say this is what moved me to agnosticism though. With that preface to my next statement; I began to realize that if I was being scientific and intellectually honest, you couldn't assume a default, there wasn't enough evidence either way to make a verdict either way and assuming a default was intellectually as faulty logic. Following up with the caveat again this is what moved me to agnosticism.
If an atheist were to say "there is scientifically absolutely no creator" then you'd be right, that would be faulty. However to say there is non required, seems to be no evidence of one, therefor I am completely emotionally and rationally convinced a creator's existance is so vastly less likely than there being no creator, that's what we generally mean by no-creator being the default. We as people tend to round up the odds when we speak about this stuff, many believers would admit it's technically possible there's no creator, but would still say they are utterly sure there is one, atheists the opposite.
It would be too tiring to sit there and figure out what each of us actually thinks the odds are in one way or the other, and then instead of calling myself atheist I'd have to call myself 99.999999999% atheist, 00.000000001% agnostic!
So one can remain "totally" atheist while still being honest about the fact that a creator cannot be disproven (by "totally" we just mean as totally as is possible, not the true scientific definition of "totally").
