I never said that. For all I know, maybe the matter and energy in the universe has existed forever. Maybe it came from nothing. But whatever happened, I have no evidence to suggest that the universe came from a supersmart superpowerful sky wizard, whose origins are no less mysterious than the origins of the universe itself.
this makes your life pointless and all mankinds life pointless
No, it makes us free to define the purpose of our own lives. We're not just pawns in a giant chess game, just toys of the magical sky wizard or characters acting out the scripted lines of the divine plan. Atheism gives us the freedom to make our own lives mean whatever we want them to mean, not whatever the gods designed it to mean.
in 3000 years the earth will be distroyed and nothing but dust all to start over all over.
Three thousand years?! Wow, that's news to me! Care to tell me where you got that information. I was under the impression that we had at least another 3 billion years before the sun expands and life is extinguished.

Face it, everything is temporary. Life is temporary. You and I are temporary. The world is in a constant state of change, and nothing can last forever, no matter how much it fantasizes about immortality.

this idea bring about the idea that distruction is life all will suffer and nothing means anything because it will all be dust once more eventuly. so life of you or i mean nothing all pointless. so in your world you should just kill off everything around you and take it all over for your self. what a crappy way to look at your self.
That's not how I think at all. Just because I'm not a slave to the purpose forced upon me by some cosmic dictator does not mean my life is pointless. It means I get to live for what I want to live for. I don't live for some barbaric ancient text, or some invisible wizard in the sky, or some imagined state of blissful immortality. I live for me, I live for my species and I live for life.

Just because life is temporary doesn't mean it's pointless. It just means that the meaning of your life exists in the present but won't exist indefinitely into the future. But you don't need to worry about that, because you're only ever going to experience the time you're alive and your life will have meaning as long as you assign meaning to it.
