Ok, well, here are my thoughts, sorry if it gets wordy
in my philosophy I believe we have some kind of energy that maintains us as a whole, the memories, the though, the feelings one have are part of that energy and it makes us who we are, a soul??, I won´t go into religion because well, I don´t believe in any religion, but allow me to make an example taking a paraphrased text out of a book of Isaac Asimov (don?t remember which one).
"in the end of all times, every human energy that existed was going into the Galactic super computer, (or something) to save at least their knowledge, at the end, one last man stood before the computer and looked back to the dying galaxy, then turned around and asked the super computer,-is there any way to stop the degeneration of all the stars in the galaxy?- the computer answered, -I am sorry, I still don´t have enough data to answer that question- so the last man entered the computer where all his thoughts and knowledge would be merged within the computer and all who entered before him, after the end, the computer was left alone in the void, where nothing existed except it, after some time, the computer came to a conclusion as to how to reverse the decay of all the stars, but there was no man to tell what that was, so the computer thought the best way to give an answer is by example, so the computer said -let there be light...-"
well, in my point of view there is something greater and more powerful than us, but in the end, it can only exist trough ourselves, which continues in a cycle of "give-take" energy from ourselves to that entity, the "GOD" concept, well, I do not portray it as the religion dictates, and the "soul" well, it is just the fuel to our emotions and our thought, am I afraid of death?? yes, I certainly am, and perhaps that is why I "need" a soul, to feel part of something greater, to have a "meaning" in my life besides just being "here" because there was some kind of explosion and we "spontaneously" started to exist, if we all did not had a soul, well, in my personal opinion we would be no more than animals... I understand that there are a lot of stupid or perverted people out there that can disprove my notion of humanity being "good" because humanity haves a "soul", but in the end I don´t believe anyone is evil, they may be sick, they may need psychiatric help, or even they might just be wrong in their way of thinking, but in the end, take away all that and you still only have a man.
I need a soul to keep going, to keep living, because in the end I will ask myself "is this it?, that is all I came here to do?, there is nothing else?, in an instant I am no more and everything I did was worthless?"
Immortality trough any means is a really lovable concept, one which I want to embrace as the circumstances come.
I hope my thougths came out as I wanted to, I am not an English Speaker, so I might be wrong in how I placed some thoughts, but thank you all who read this
