Did sin really separate us from God?

Or was it a natural process when life within organisms was created and upon death the life within naturally returns back to where it originally came from - God?

(that is if you believe there is life within us and that it originally came from somewhere called God)

No, there's not God.

When you die you are just plain dead no more sinning for you! And BTW God is a superstition!

Sorry.

something created matter with life within it. it just didn't happen. the term God has been given so many different arttributes and characteristics that are specific to different religious beliefs it is no wonder that there is mistrust in its existence

which god are we referrig to here? christian god i am assuming, but please make it clear

Not the religious God because that is where all of the confusion comes from. The Christian God has different attributes and characteristics from the Muslim God, and the Hindu God, and the Sikh God.

What I am referring to is that "something" that started it all.

Not necesarily,
I see no reason to think life had to be 'created', we work on the same chemical reaction and processes as the rest of the world.

Perhaps the life that exists today in organisms is life that was received from the organisms that created them. I am not aware of anyone who has created life from dead matter. Perhaps there was, in the beginning, a big bang that created matter with some matter capable of housing life within and that ever since then everything else has been evolutionary.

What is sin? Hurting someone can be an accident or deliberate. I think telling someone what, at the time we thought was 'the truth' was no lie even if later the statement was found to be an error. Also the part quotation "To err is human" I forget what this quote has to be devine!

I think sin is a term created by human beings as an explaination to what appears to be bad, or evil, or wrong, ... I am not sure that good and evil, right and wrong, positive and negative, left and right, etc exist in my concept of that "something" that created it all. I think that dualities exist in the dimensional worlds.
