Physically we are eternal

[JerryG]

How can we define outselves? We are a body defined by our DNA number. If we are a twin we are a duplicate. In that case two of us exist at the same time .
Throughout the universe there are a huge amount of Earths with man. The universe cycles forever. Thus man and beast have always been and always will be. This means that our DNA code will eventually return over and over again perpetually.
Our code could be produced with similar but different parents. Our mothers and fathers would be different upon different planets. Our lives would be different.
We could argue that we are our bodies and our lives. Thus it is virtually impossible that our life will be recreated. Yet given eternity this could happen. In general we will live and infinite number of different lives for every repeat life.
Our soul and Godspirit belongs to God and not us. It is a interaction between our physical bodies and Gods energy. Yet when we die, we are no more and our spiritual energy returns to God. Thus in death we are no more, yet we will be born over and over again. There is no escape from cosmic rebirth.
It is upsetting to realize that at this very moment, our duplicates exist in far away planets and we have no way to say hello. Only God knows all of us.
