Life

Life. What is life? Are there qualifications for living. For example, do you have to be breathing on your own to be considered full of life?
Is life something science can explain or is it some unexplainable force?
Where does life come from? Is it what those of faith say and a divine gift or is it just some random cosmic accurance that happened totally by accident?
Everytime I start thinking on the topic of life I think of where life comes from and all that surrounds it. Such as, personality or your soul. How do you explain that?
Also, when I think of life I think of death.
I myself am an atheist and therefore I don't believe in an after life but I can't help but wonder, what happens when we die? Do we just become nothing? Nothing but a dark abyss and memories that will soon fade when the ones that kept them pass on also?
Or, are the Christians and others of religion correct when they speak of a "Heaven"? Is there truely such a wonderous place full of nothing but bliss and the miraculously healed loved ones that left us all to soon?
It frusterates me because that is an unanswerable question. No one has come back from the dead, well unless you count Christ, but that's only for those of you who are Christian or Catholic or whatever it's called.
Well, I think I covered all I wanted to cover for now.
Thank you for taking time out of your day to read.
Yours Always,
