Halcon: I would say the most important and crucial facet of our lives is the present, the here and now.
If we lack an eternal future, then I agree. But if this life is a microscopically tiny portion of my overall existence, then its importance is equally minor. Not knowing what is next would be a major concern. When I was a believer, my presuppositions provided some comfort, because I could ignore the problems with the way we defined God. The version of God that Christianity has constructed over the centuries is very unsettling if we remove the presuppositions that are in direct contrast with how he has been defined.
Duran: who's version of good and bad, right and wrong would be correct in your way of thinking?
Well, I would ask you: is it possible to explain why murder, theft, deception, or rape are wrong? Do you believe that these actions are inherently neutral, and only immoral because God says they are? Is there no basis upon which we could build a moral foundation without God?
