Since proving a universal negative, that there is no God, would be impossible to do for anybody unless they were God, atheists have strayed from the definition of their worldview. Whereas 'lacking God belief,' falls short of the historic definition of atheism, it is sufficient for exposing the failures of all atheistic beliefs. More specific questions will be posed to the more specific atheistic worldviews.
Q: If there is no God, where did the universe come from?
Q: How do you justify universal, immaterial, unchanging laws in your version of the universe?
Q: What gives humans dignity over any other advanced primordial slime? Why do you attend the funeral of a human, but not have a funeral for a fly or a virus or a cancererous cell?
Empiricists claim that all knowledge is gained and verified by the senses, or that all knowledge is limited to observation. In the most basic form, Empiricists claim that "Seeing is believing."
Q: By which of your senses did you come to know that all knowledge is verified by the senses?
Moral relativists believe that morality is not universal but relative to the culture. In other words, "When in Rome, do as the Romans do."
Q: Since you do not claim objective truth, why should anyone believe you?
Q: Is it objectively true that morality is relative?
Pragmatists believe that all they require is success in achieving their goals to determine what is right. Whatever has been successful in controlling their environment is the chief concern of pragmatists.
Q: What are the proper goals in life?
Those who profess mystic worldviews put the emphasis on that which is beyond human experience and can only be known mystically, not rationally.
Q: If your worldview is beyond rationality and human experience, how do you know about it?
Q: Is not anything you try to tell me about your worldview based on rationality and your human experience?
Q: How do you know your worldview is true?
Q: Where did the universe come from?
Hindus believe that "all is one,' and that Brahman (God) is everything. Since it does not appear that way to us, they say that Brahman is beyond our experience and rationality, and all that we experience is illusion (maya).
Hindus claim that the only way to get right with 'the all' is through mystical contemplation such as yoga, and meditation, so that we can be enlightened to the truth that we are one with the sky, the trees, the lake etc. Hindus claim that the problems with this world stem from our belief in distinctions rather than the oneness of being and that once enlightened, we will escape the cycle of reincarnation, and enter into 'Nirvana' as a drop of water into a shoreless ocean.
Q: If as you claim God is not personal, is your holy book, the bhagavad gita, a personal revelation from God, and, if not, why should anyone believe it?
Q: If any distinctions between you and a truck are illusory, why do you look both ways before you cross the street?
Q: If all is one, and there are no distinctions, am I not in Nirvana already?
Moralistic worldviews do not have a transcendent authority which to appeal to. In moralistic worldviews 'God' and 'Heaven' are usually lumped together and range in description from an abstract void to an impersonal principle (Nirvana in Buddhism and T'ien in Confucianism). Most moralistic worldviews claim that the problem with humanity is that we fail to live up to a particular moral code and that we need to try harder to live up to that code to attain some form of 'enlightenment.'
Q: Where did the universe come from?
Q: If I was unable to live up to this code in the past, how will I be able to 'try harder' now?
Q: If I have broken this moral code in the past, how is the guilt of my past deeds dealt with?
Q: What gives Buddha, or your holy books authority?
Q: How do I know that Buddha is the enlightened one, rather than Confucius?
Q: If anyone can get to 'heaven' by just being good, who determines what 'being good' is?
Q: What gives Confucius or your 'holy' books authority?
Q: How do I know that Confucius is the enlightened one rather than Buddha?
Q: By what authority do you claim that Confucius was wise and what determines what wisdom is?
Christian Counterfeit worldviews regard some or all of the Bible as authoritative but then through claimed 'additional revelations,' reject the most basic teachings of the Bible. Some are polytheistic (believe in many Gods - as the Mormons do), Unitarian (rejecting the trinity as most Christian counterfeits do - including Islam), and some have perversions of a false Messiah.
Q: What is the manuscript evidence for the multitude of discrepancies between the Mormon bible (which teaches for instance that Satan offered to redeem mankind, that Adam was baptized by immersion, and that a prophet named Joseph Smith would appear), and the Christian Bible.
Q: What is your answer to the teaching in Revelation 22 vs. 18 that anyone who adds or takes away from the Bible will be dealt with plagues and banishment?
Q: How do we know that the Mormon version of the Bible is true?
Q: What is the evidence that the original language of the Book of Mormon "reformed Egyptian," ever existed?
Q: Would a true prophet of God have been convicted of 'glass looking,' (a con of placing a 'magic stone' in a hat, placing one's face in the hat, and by that means locating hidden treasures), in Bainbridge New York, on March 20, 1826, as Joseph Smith was?
Q: Does your organization claim to be a prophet of God?
Q: Since Deuteronomy 18 vs. 20 -22 describe a false prophet as one who gives a prophecy which does not come true, how do you answer the prophecies of the Jehovah's Witness of the end of the world in 1914, and the bodily return of Abraham, Isaac, and Jacob, in 1925?
Q: What is the manuscript evidence for the discrepancies between the Jehovah's Witness' 'New World Translation' Bible and the Bible of Christianity?
Q: Since the Koran (Qur'an) acknowledged the words of Abrahm, Isaac, Jacob, Moses, David, Jesus and His apostles as authoritative (Surah 2:136, 17:55), how do you account for the conflicts between the Bible and the Koran such as the Koran's claim that Jesus was not crucified? (Surah 4:157)
Q: Since the Koran was written around 600 AD, a time when current manuscripts of the Christian Bible were available, what is the evidence that the Christian Bible has been corrupted SINCE then?
Q: SInce the Koran claims that the words of Allah cannot be changed (Surah 6:34, 6:115), how do you support your position that the previous words of Allah in the 'Book' (the Bible) have been changed?
Q: If Islam claims to be a peaceful religion, how do you account for the verses in the Koran such as this one from Surah 9:5 "Then, when the sacred months have passed, slay the idolaters wherever ye find them, and take them (captive), and besiege them, and prepare for them each ambush. But if they repent and establish worship and pay the poor-due, then leave their way free. Lo! Allah is Forgiving, Merciful."
Q: How do you account for the claim in the Koran that Mary the mother of Jesus was the sister of Aaron since they lived hundreds of years apart? (Surah 19 27-28)
Q: Do you believe, as stated in the Hadith book of Sahîh al-Bukhârî Volume 4, Book 55, Number 543 that Adam was 60 cubits (90 feet) tall?
