The atheist has nothing to live for because in the end there is nothing. Expressed in Groundhog Day by Bill Murray, if there is no tomorrow, there are no consequences for today.

Some will live an ethical life because they feel it is the right thing to do. Others will strive to create a heaven on earth because that's all there is. (Lenin, Stalin, Mao, Obama)

I think you miss an important point.

There is no point to humanity in living “ethical lives” absent a certainty that there exists a conflict of good versus evil.
