As an atheist, I won't criticize you for your statement. What you said is very understandable.. What about the meaning of life, you say. Well as an atheist I really don't care to find one... Asking me "what about the meaning of life" is like asking me to divide by zero... Does not compute... But for me this isn't a "glass half empty" situation, it's never gonna be "oh life is meaningless I'm gonna end it right now since it's dumb anyway".
I always say "life is meaningless, so what?" Let's just enjoy the ride, even if the bus goes nowhere interesting. Even better, let's take the wheel and see what happens!!
