When did this all begin?

As I went to sleep the other night I began to wonder about how much importance we give in life to what we do, what we say, what we own and don't about our theories and our vehemence in proving them right or wrong.

It led me to think about our theory of evolution and how it does not agree with the religion. It led me to think about what is all this life all about? What is life?
What is the difference between me and a corpse - the Breathe! It led me to wonder if we have discovered as yet the means to create life! How can one possibly create something that is living? What is it that brings about life? And then I was overcome in this overwhelming feeling of awe - it just seems to be impossible to create life!
My body right now moves around because it is living - and I am limited only by what I think. Which means we are all capable of doing so many things - being whatever we want to be. And yet at the end of the day what does this all lead to? What does it mean to die? What does it mean to be born? When did I take birth - when my first cell was formed in the womb? But then the cell was living in my mothers body long before that. Infact all the egg cells lie in a dormant state of life and are released once a girl reaches puberty. So then my living cell was in existence since my mother was born, which means that her cell was living even before...what does this mean? I have been in existence all this while?
My mind could not wrap itself around this idea - and it brought new meaning to living for all eternity! So what does it mean to die? Does it put an end to this existence of life? I need to read more - not sure how I got into such philosophy!
