@John Creasy,
Why be a good person? Because I don't need God or a religion to tell me how to be kind and just. My parents raised me well. I'm Aethiest but what does that matter? It just means I have a brain I know how to use.
You're right though, this all is just a "cosmic fluke." Life is pointless, nothing matters. I take that as...live each day like it's your last. When all is said and done, if you look 100 years from now...whatever you did or did not do during your life doesn't matter.
Humans are simply a series of memories. Memories create our personalities and develop our brain. Create the best memories you can. Don't need God to tell me that.
