Disproving God is impossible. We see and hear and we cannot do much about that. We cannot stop hearing. We are tested and challenged by God by the very fact of our own existence.
I have never been an atheist. But for several years in my life I did not take the issue of God seriously. In a manner I was a non-believer. Today I have a strong belief in God and I know well what positive impact it has on my personal life. I simply cannot imagine losing faith.
It is impossible to disprove God. Learn more, ask, read, discuss, open your heart, start doing good for God's sake and for the beautiful eternal after-life. After you have gained some belief, have a conversation about God, life and creation with one or two friends (believers). As you do that enjoy the blessing and the spirit that God's sends down on a meeting of that sort. You will sense it in your heart. When you experience that you will know that God is the truth. As you experience that you will start longing to meet the Lord of the Heavens and earth (see note below).
Information: There are 7 Heavens (according to Scripture). We can see only one of them. Scientists call it the observable universe and it is 879,847,933,949,940,000,000,000 KM in diameter. In other words, almost One Million Million Million Million times the distance to your work / university (if the distance is equal to one kilometer).
Best wishes.
