re: A fact worth remembering: Those who don't believe in God argue against absolutes

I don’t believe in God and have no problem enjoying life. There doesn’t need to be any absolute, objective moral truths or eternal meaning to existence in order to experience subjective happiness. And ultimately, while there is no such this as “good” and “evil” in an absolute sense, there are behaviors that objectively harm and objectively benefit the society in which we have created. If the goal is to maximize human happiness and minimize suffering, then we can say there are actions and behaviors we should encourage and those we should discourage. That is the basis of our legal system.

So if you want what you do to matter 4 billion years from now then sorry, it won’t. But what you do and how you live now does matter, and a lack of eternal purpose doesn’t change that.
