It should be realised that there are three kinds of atheists:
First, there are those who believe that the existence of God is not established; i.e. they do not believe in God because they have no strong and convincing evidence to prove His existence. Such atheists are the majority and I think that more than 90% of the atheists fall in this category.
Second, there are those who hold the belief that existence of God can neither be proved nor disproved and, therefore, the issue cannot be resolved with arguments. For all practical purposes, these people too do not believe in God.
Third, there are those who believe that there is no God; i.e. the non-existence of God is established by conclusive arguments. All the same, they really base their belief not on such arguments, but on the assertion that there is no evidence for the existence of God. However, they present some arguments only incidentally. These people form a small minority, and probably account for less than one percent of all atheists.
The stand of the three groups can be summarised as ‘rejection due to lack of proof ’, ‘rejection and denial due to the lack of possibility of proof or disproof ’, and ‘rejection due to proof of non-existence’, in this order. The first group is the largest in number, the third are very few in number, and the second are a little more than [the third]. The atheists in Europe and America have chosen for themselves the name ‘agnostics’, which literally means that they just do not know. They have taken the stand that they have no evidence of the existence of God; not that they have proof of His non-existence. Thus, a large majority of atheists do not believe in God because they have no evidence of His existence. Here it is not our purpose to refute the beliefs of these people, because the refutation of this stand covers this presentation so far, supplementing each positive argument by dismissing various doubts. Other positive arguments relating to the next section will, God willing, be stated as and when appropriate. The same applies to the refutation of views of the second category. Here, I intend to refute the ideas of the third group who claim that non-existence of God is established by arguments. I will only state facts which have not been mentioned above, avoiding any unnecessary repetition. Such atheists put forward the following arguments in support of their belief.
