I quote Bad Astronomy
If I do think the Universe is accidental, that does not mean there is no rhyme or reason all of science depends on the Universe obeying a set of rules (even if the rules are hidden, or hard to understand, or involve seemingly random events as quantum mechanics does). So right away, even if I do think the Universe is accidental, I would say that quotation is going too far and is wrongheaded, but not in the way the quiz means.
I also may not think life on Earth is inconsequential. I have heard this many times from religious people talking to atheists: how can you cherish life if you dont believe in God? I find that question pretty funny, actually! The mindset is, if atheists dont cherish life, what is to keep them from simply murdering anyone who ticks them off?
The answer is that atheists, as well as believers, have evolved a sense of morality over millions of years. Mammals tend to be family-oriented, and primates very much so. Tribal customs evolved to aid survival, which means helping others when needed. Its not hard to get an idea of how morality evolved from that, although of course I am grossly oversimplifying things here.
If you think this is wrong, then consider this: if no God means no morality, then youd expect atheists to commit more crimes. Yet, if you look at prison statistics, atheists are grossly underrepresented in jail. Only 0.21% of prisoners are atheists, though in the US some 3-9% of the population call themselves atheists. If religious people were more moral than atheists, then youd expect the number of atheists in prison to be much higher than their percentage in the population. Yet the opposite is true. This means that atheists commit proportionately fewer crimes than religious people (well, it really means that atheists are caught and successfully prosecuted less, but one can assume those numbers scale with the numbers of crimes committed).
Are atheists more moral than believers? Thats a hard jump to make. But those numbers are very interesting.
