The analogy works just fine, because the items in the bucket (concept of human rights) were never ultimately contingent on the bucket (concept of God) but rather on the owner (humanity). It might be accurate to say, however, that the owner did once think that the bucket was required to carry the items. In fact, it may very well even be true that the owner would've never been willing to carry the items without the bucket. It may still be true to an extent.
Someday humanity will grow up. ;)
I understand, but I was looking at this sequence:
God is used to explain the creation of the universe and everything in it. If God is removed, it seems to me by your original words, then it must be man that created the universe and everything in it. That is absurd. Do you mean just non-material things, like morality, sense of beauty, evil, etc.?
