Briefly, whatever the truth may be about a "Creator" I do not think that anyone sane and reasonable can argue that evil does not exist in the world? Therefore, if evil is a fact, surely goodness also exists?
Even is we just want to think from a "Humanist" perspective and leave religion and "G-d" out of the discussion, my question to you all is this: why cannot we just live in peacefulness and be decent to one another - including all the animals on this planet? Whether we like it or not we are stuck here living our lives - some living the most appalling miserable lives (maybe I should say "most people" including the total population of the planet.)
Why must we let suffering continue in all its forms? Let us try to do "good" things for one another, for all the animals, and especially for this planet which sustains our lives. After all, some of us are here for quite a long time - might as well then make life more bearable - no?
Finally, we have the question of "love". What is this? Is it "real"? Most people talk about it. Most people seek it. Even if we cannot "love" each other we have the choice to try and leave each other alone in peace and stop doing evil things. Meanwhile it is very good that we discuss together and think about these things - whatever our viewpoint.
