Are humans more insignificant to Atheists or Theists?

[Cecelia]

Human life is considered more valuable to Atheists, but Humans are more significant to theists.

Atheists see that human life is all we get, and therefore we must live it to it's fullest.
Theists believe that the universe was created for them and them alone.

Of course they call us arrogant, though they're the ones who think that an almighty creator made them special.
