Sometimes I think what we've been fed as JWs (or many other religions for that matter.. ie heaven or hell) has distorted our view of God. I am beginning now to see the difference between the Jesus of the NT and the God of the OT. Jesus said that any who have seen him have seen the Father also. Yet there is much in the OT that shows God in a opposite way. A God to be feared and not loved. I think man's way of visualising who and what God is have distorted him. Also what the bible has to say about creation is obviously not to be taken literally and is actually very limited in what it does say. Man has filled in all the gaps and has come up with something that science has shown isn't possible. It doesn't mean that there is no God or there is no creation.
However what I would say to you as an atheist (and it goes for all of us)... enjoy your life now! Enjoy every moment. Thinking about dying can spoil your enjoyment of the life you have! One guy whose blog I read sometimes said a few days ago:-
"So as we approach a day of giving thanks as well as the start of a new calendar year(which is meaningless by the way, every day is worth making that special), i cannot help but step back and realize that I need to make a conscious effort to invite those feeling of simplicity back into my life.Carrying out, with pride and excellence your adult responsibilities while living life with a childlike passion and simplicity is, in my opinion, the goal of any well led and full life.I sit here with a choice to make this day routine or make it extraordinary...but words are not enough. At the end of the day, I must be able to prove to myself that it was a well-lived day."
