All I'm getting from you is a lack of belief...because you haven't seen a ghost.
Let's flip the coin.
You think life has an end.
Why do you think God set it in motion in the first place?
It was you who suggested you can make an argument FOR God
I've been seeing "ghosts" for as long as I can remember. My whole family does, and many of my friends have experienced them in my very "active" house. That doesn't prove God at all, maybe supports an afterlife. I have two much more acceptable ideas of what is going on though that require neither.
I, personally, do not think there is a God at all. But arguing for, I would have to say that the reason God created at all is to have something to teach / fill. If there is this conscious, infinite, all powerful, etc energy it would probably wish to share it's knowledge. So, it makes a lesser God to create the material world, makes angels, makes man and gives us the two paths which I spoke about earlier. So, the meaning of life would be knowledge / reconnection. And yes, if I believed in God I would be Gnostic.
