Meanwhile, the atheist lives his or her life without a god, or as if there were no God. Although the atheist does not dogmatically say that no God is possible, the atheist thinks that it is highly improbable that there is one. Atheists know that there are lots of difficult problems facing mankind. Without a god, humans are the only source of solutions. Past generations have devoted their lives to improving conditions here on earth.
Present humans continue in that quest for the sake of themselves and future generations.
Atheists do this by feeding the hungry, clothing the naked, improving health, etc. Each person can contribute up to the limit of his or her abilities. We become happy by making other people happy. Atheists reply that if you need religion, and such belief makes you happy, then you have the right to be religious. Atheists are for total religious liberty.
