Actually, praying could prove there is a god if it is answered.
Praying is an act made by your subconscious mind.
The fact that any "prayer" is answered at all is simply coincidence.
Another flaw: "if"
Even a man of God who has never committed sin in his life span can easily be ignored by your supposed "deity".
He could pray to be saved as he is being brutally beaten, but nothing comes and he is murdered on the spot.
You christians sit by idly and play the "if" card every time, acting like it's a game of chance based on your Karma status with a fake deity.
You all say "God makes us in his image"
Then why is obesity the #1 health issue in America? Does this make God's image a disgusting, fat pig who sharts his pants every time he eats?
Why did your God not do anything when thousands died on September 11th, 2001?
Why did that student get away with killing so many at Virginia Tech?
Why?
I used to be brainwashed by my parents when I was growing up to believe in Christianity.
I prayed.
Why did nothing happen? I remember every single prayer I ever made when I was a boy.
Here I am. 21 years old and none of them have ever been answered.
They were simple, small prayers. I was a good boy. I rarely "sinned" or even said a swear word. And when I did, I asked for forgiveness.
Nothing. Happened.
Your God. Is false.
Your religion. Is broken.
