Every Atheist May Have Their Own Reasons That Do Not Believe in the Existence of God. 

Every atheist may have their own reasons that do not believe in the existence of God. 

Some of them deny the existence of God based on the view of philosophical. 

Some of them compare the "evidence" for the existence of God, but thay think that there is insufficient evidence

Some study some religious scriptures, and think that the content is ridiculous and deny the existence of God. 

Some have not even been thinking on philosophy, theology, but rather deny the existence of God based on their self-experience.

Dont believe a thing is true, doesnt mean that it is false

The atheist believes that the universe all belong to nature, only the presence of known and unknown. So, they do not believe the god and supernatural.

The theist often attempt to change the atheist point of view, they think that god created the universe, but they always can’t prove it with convincing evidence.

In order to avoid complete denial, they often respond: Since science cannot prove God does not exist, then it should be assumed that the existence of God

True things can never be disproven and false things can never be proven.

Most atheists and theists passively get their concept of God is through family and social.

But they never stand on a view of rational, philosophical speculation through in-depth and their own perception to determine the existence of God.

Atheist “don’t believe” GOD is because they deny the evidence, Theist "believe" because there is evidence. 

Atheists don’t believe in the existence of God, but they may not completely deny the possibility of the existence of God,

Just that so far no method makes people believe that this possibility or they think that humans can not know whether God is exists.

If you believe in God, then God exists. If not, then God is just a character in the story.

Do not Over-reliance on some external forces, do not worship authority, to be rational to believe in yourself
