Wow, I am surprised by the high amount of scientific, no soul responses as well.
When I was younger, I definitely firmly believed in Heaven and Hell. However, I now completely reject the idea of Hell, as it seems to make little sense to me, especially if it includes sending someone there just because they didn't pick the "right" religion in their lifetime. After my cat died over ten years ago, I started telling God to tell her that I miss her. And I still continue to do this every night. So I guess that means I believe in Heaven.
As a side note:
The strict science approach to life never really made sense to me. Why does anything exist in the first place? I guess religions and science both kind of lack an answer to this question. I actually find the concepts of "forever" and "existence" to be much more terrifying than the concept of dying.
Both sides of the idea of creation, one of which must be true, are equally baffling. Ok, big bang. Ok, God. But what about before that? And before that? Does it just keep going back forever? Why does anything exist at all? Has something always existed and will something always continue to exist, or was it created at some point? It must have started sometime, right? But then, what caused that? Its very circular reasoning that really has no way of being explained through science or religion. I once discussed this topic with someone and they said they believe that the only reason it seems that things must have a beginning and an end is because we are humans who can't fathom such matters. As in, God is beyond the comprehension of man. I still haven't quite decided whether or not I agree with this concept.
But yeah, anyway. Death seems kind of small to me when I think of things on a bigger scale. Sorry I went off on a tangent a bit, but I feel like it is closely related to the topic question.
And just in case anyone religious reads this and thinks its blasphemous, note that I do consider myself a Christian. The idea of atheism bothers me for some reason. Really? Life has no point and there is no chance that it could have any meaning? I can't buy into that.
