Wooooooah! Dude! The photo is a joke. That is more than obvious. Chill man! No need to get your panties in a riot!
You are right, we have nothing to die for, as for death s the end of life. Therefor, we have everything to live for. We live because life is our treasure. We live because this is it, as a difference to religious people that live, to then die and "Live forever." So in that case, they live to die. We live because we only get one chance at life.
And by we I mean atheist!
How can you say that you are going to teach someone the truth when it's only a theory. Because at the end of the day, every idea about life and where we come from of where we go is just a theory. The creation theory, the big bang theory, the evolution theory, the Buddhist theory. They are all theories with their amount of "evidence" to each. I think that's the problem with humanity, we talk about facts when it's just opinions.
Why not? If they want to! They can do what the want! If a teenager can smoke pot with nobody bitting their ass, why can's grandmas do it too. That is if they are not forced!
It's just a phrase. We grow up saying lots of phrases that most of we don't take seriously.
