It is good that you are looking for answers, and not just believing because people tell you it is true...
The fact that you are here and asking shows that you have some desire to believe.. that there is something in you that is drawn to the idea of God.
I was an atheist for a long time.. but something in me always felt there was a missing part, that there had to be 'more' somehow. As a scientist, I didn't like the concept of God, didn't think that I needed anything that couldn't be proved.
And yet, there was always that emptiness. That eventually led me to read and explore the concept of God. I read a lot about different religions, but Christianity was the only one that really seemed to resonate with the need in my heart/soul. I didn't 'want' it to be true, intellectually.. and yet it was.
And it remains so. I have been through some hard times, I have felt a long way from God, I have wandered off into my own thing and not done what He wanted, but every time, He has been there, He has brought me back and helped me to grow and to keep on.
It isn't something which can be explained 'rationally' or proved empirically, I can't show you concrete evidence, and yet God is more real than anything else in my life, and I know that He is there.
The atheistic explanations may be more logical, but they don't fill the hole at the centre of the human heart.
