So i understand the question is "why am i conciousnessly(sp?) existing ?" Or something like that.
First of all what makes you so sure you exist ?

... I'm joking, i don't want to start that reality crap.
If you would find the reason for your existence then what other pointless question will you wonder all your life ? ...
Here's one of those stories Buddha said to one of his follower.
It's not a religious answer - read it.
This follower of his was really confused because Buddha didn't answer some fundamental questions like the one you are asking yourself. So his master taled him the story of the man hit by a poison arrow.
So there's this guy that was hit by a poison arrow who refuses to be treated by a doctor untill he knows who his atacker was, where does he live, who are his children, why did he shoot him, ... and so on ...
Of course the poisoned guy can never find the answer to
ALL his questions untill he dies. But if he did knew the answers would it really matter ?
That is the condition YOU are in. Those kinds of questions you ask yourself are the questions of the poisoned man. The poison is DEATH, and it will come in 70-80 years ... You are cannot find the answers to all your questions untill then.
But if you actually find the answers to -some- of them, will they really matter ?
Turner said:
Sometimes it's not the destination, but the voyage, that matters.
Amen to that.
You don't need to know these things, it's ok if you don't. Nobody knows squat about it. We are just improvising "on the way there".
Nobody has a clue where this life will take them ... you shouldn't try to look for the road to the end, you should build it.
Also, one of my favorite funny quotes fits in this case :
"We have no idea what we are doing, but it's fun."
Note:
He asked for a non-religious answer. So don't start ranting about how predeterminism contradicts what i said.
