Are there any real athiests?

An atheist is one who says that he knows there is no God. Obviously this statement is unsupportable because no human being has knowledge of everything. Our knowledge, no matter how vast, is greatly miniscule compared to the vast amount of knowledge we are ignorant of in our universe. So there is a possibility that God exists in the realm of what we do not know. So there really is no such thing as an atheist because no one can know for certain that God does not exist.
 
There are, however, many agnostics. The word "agnostic" means "without knowledge". They do not know that God exists. In reality, they are doubters because they are not convinced that God exists. There are, however, two different kinds of doubters: honest doubters and dishonest doubters. If a person doubts that God exists and he is honest, then he will search to find out if God exists. A dishonest doubter is not interested in finding out if God exists. Dishonest doubters want to remain in their doubt because believing in God would mean that they would be accountable to God for their deeds, choices and lifestyles. Jesus said in John 3:19-21 (NKJV), "And this is the condemnation, that the light has come into the world, and men loved darkness rather than light, because their deeds were evil. For everyone practicing evil hates the light and does not come to the light, lest his deeds should be exposed. But he who does the truth comes to the light, that his deeds may be clearly seen, that they have been done in God.”  An agnostic can find out if he or she is an honest doubter or a dishonest doubter. An honest doubter will be willing to genuinely pray this prayer (they don't have to be convinced that God exists to pray this prayer): "God, I don't know if You are real, but I want to know if You are real. I don't know if the Bible is true, but I want to know if the Bible is true. I don't know if Jesus is Your Son, but I want to know if Jesus is Your Son. I don't know if there is life after death, but I want to know if there is life after death. I don't know if my life has meaning, but I want to know if my life has meaning. I am open to discover whether You are real or not, if the Bible is true, if Jesus is Your Son, if there is life after death, and if my life has meaning. I am willing to follow the evidence no matter where it takes me, how it might challenge me, and what it will cost me."
 
The best place to start looking for answers is reading the Gospel of John because it was written for this specific purpose: "that you may believe that Jesus is the Christ, the Son of God, and that believing you may have life in His name." (John 20:31)
