Atheists can love... and it's a movie not something to base your life around.

Still though, I found it to be extremely emotional and touching.

I don't remember saying atheists can't love. Nor did I say that film is something to base one's life on. What I am saying is this: we all hope to some extent that love reaches deeper than our understanding, that it can bring us truth that science alone cannot. Most religious people embrace this, while atheists will value love for its evolutionary/survival value, but ultimately "know" that humanity is a single species on a small planet orbiting an average sized star in a smaller than average galaxy out of billions of galaxies, and that our love does not surpass the cold, harsh reality imposed by science.

This movie exemplifies that hope that I think most of us really have. People want to have faith in something greater, even if they do not actually have such faith.
