Are athiests thankful for the good in their life?

It would be ignorant to say people aren't thankful for the good that's in their lives based off they're beliefs. People say that because they just flat out don't like athiest or people with different beliefs are bad people. All that matters is whether or not a person is a good person and lives a good life, not whether or not they believe in a higher power. Happiness has nothing to do with a person's beliefs. Some people actually are more happier not religious than religious, because they don't have the burden of worrying about everything being a sin and displeasing god.
