@Lou, it is good to hear that you do have beliefs.
Now talking about an imaginary future. It seems to me that people are always looking to the future, which since it is still in the future, is “imaginary.” Also it seems that we should be building a future that we would want, not a future that is evil, so living for a imaginary future is good, not wrong.
The reality is that we live only once and are gone, and you are right, this means that we must make the best of our time here. The reality also is that what we do now, we are responsible for. In my opinion God’s Reality, that you do not accept, holds us to be responsible for what we do and who we are, rather than enjoy our failure to treat other people fairly or simply suffer for the short term unfairness of the world.
It seems to me that if you are really concerned about the apparent unjust nature of life, then you would be a supporter of heaven rather than a critic.
There is no real scientific consensus of what life really is, in terms of what is good and right. Our friend Caleb said that the Golden Rule was a good start, but it comes from the Bible, so it is rooted in myth. Besides it makes me feel good about myself, so there must be something wrong with it.
When I talk about God, I am talking about a world view about what the world really is. If God is Love, that means God’s world has a particular character where the Golden Rule works. If God is Logos, rational Truth, then God’s Creation has a particular character where people need to be honest and fair. These are falsifiable statements, and they are not false.
I cannot say I understand how one can say that atheism allows one to see the world as it really is, because atheism is not a statement of what is, but what is not. To me it means that there is no rational purpose behind the universe and reality, so life logically is random without rational purpose and meaning.
Thus per atheism we are here to survive for no reason, but since life without purpose and reason is per se evil, suicide is the rational alternative to life. Of course science cannot exist without a rational universe.
