Atheists do you really believe that NOTHING becomes of our consciousness after death?

That's why agnostics are generally wiser -- they're playing it safe and they honestly don't know what happens and they don't pretend otherwise... Atheists say they "don't know" yet they're so quick to tell you that there is no God and that nothing becomes of us after death... I think there has to be something out there beyond human comprehension that becomes of our consciousness after death. We know so little about our existence and the universe that anything can be possible.
