What is the reason you are alive?
Definitions, words, are all made by us. To say that I'm alive would mean there are things I can differentiate myself from, hence assigning it a word that explains my state of being "alive" so the key factor in calling something alive, is that it's properties are different, hence things that which are "not alive" decided the creation of this word. What makes us us, is that which is not us...
"What is the reason you're alive?"
We all have a purpose on this Earth. There's no denying that. However, not everybody knows they have a purpose, and not everybody has discovered their purpose yet. I haven't discovered my purpose yet, however I'm always told my purpose is keeping people happy and smiling. That is a purpose. Being told that, I may now face the inevitability of death knowing I have a purpose, and I've benefit someone.
The reason we are alive is to fulfill our purpose, whether it be big or small. There's no actual scientific reason for our existence, and why we're here, however know you have a purpose and you're unique amongst the sea of human kind.
God only does virgin births. Tapping a used one would be kind of unholy, according to many Christians. I've found few (no) virgins with kids, and most of the non-virgins were little devils! (Most of the kids too)!But then, God created the devil, hmmm, very confusing, wish I could continue my research, but, alas, I have been "alive" too long. ;-(
