Well... (sorry for my english)
I would like to write sooo much about this topic...
I am somekind of atheist, I don't belive in any great power or such things. Still, I think there are many things that science has not touched yet. For me, religions cover the weakness of human mind. Because is really hard sometimes when you do not believe in anything, really hard. It's hard to believe that when you'd die, there would be nothing, in fact, it causes me great pain when I think seriously about it. But at least, when I die, I won't notice that, as I will be pretty dead xD. I really would like to actually belive in some god, or anything but cold-science only, but i can't (the story about the bible is what someone has posted before: if you tell someone who tells someone who tells somen... the last one has a different story)
But yeah, life can be created (they've posted it, that history about the aminoacids). So, life it's actually a "definition". If you know something about viruses, the frontier between life and death becomes to blur significatively. Life is no more than a system or union of things. In fact, we all are small ecosystems. We demominate life that one s based in carbon, but I think this is a narrow vision of reality.
The story about suicides is pretty logical. Life is completely senseless. The existence itself is senseless. What's more, if you believe in any religion, immortality is completely senseless. Imagine you life for the rest of the eternity... It would be horrible (well, firstly it'd be incredibly boring). It's even more hard to believe than there's nothing after life. And, If you're religion does not belive in immortality, it's the same story as the atheists.
I said in my first paragraph that I think that sciece has to evolve so much because I belive there's much more than our eyes can see or our ears can listen (and I'm not talking about the colors we don't see or the frequencies we can't hear). Some psycologists have investigated that thing of the tunnel and the light when someone is between death and life. It seems it like we had like a common inteligence that guides us all, as in the ants (one ant alone will irremediably die, but as you add more friends to the first, the seem to be more and more intelligent and organised). I was clinically dead for 5 minutes when I was young so I'm really interested in this topic (clinically dead is no pulse, no respiration, nothing but cerebral death)
One physical note: There are particles that go to the past, i. e., tachyons (I think this is the word in English). Relativist theories demostrate that any particle beyond lightspeed move in time in the oppositte direction in that we move. Thats the primarily reason why the ligthspeed is a constant, is the frontier (I can't find a word, sorry for my english), the "zero" in the "axis of time" between "the go to the future" and "go to the past". This particles have been detected in nuclear centrals. They can´t be seen phisically ( In fact, if we believe in our hated friend heisenberg, it's impossible in any way that we know where are they), but they emit a glow (I don't remember the specific name of it). It has been demostrated that their minimum speed is lightspeed (it more like a limit, an asintothe (once more, i don't know the english word). So well, they open more and more questions (wether they go ahead or back in time).
Quatum theory just don't say anything about them, so it's like an acceptance I suppose (and well, since it is the most advanced human theory, this is kind of important). Scientifically speaking, we are just non-linear time functions, the same we have in mathematics in fuction of x, y and z axis (or the equation of a wave in n-dimensions for example)
