Had to break it into two sections:

#9: If God created time and space, he must live outside of time and space. Thus he is non-existent.

The logical conclusion is that God must live outside of our dimensions of time and space in addition to living within our dimensions of time and space. The unstated assumption that God cannot live both within and outside space and time simultaneously is false. Since science tells us for God to exist and to have created the universe, He must exist in at least 11 dimensions of space and time (the four within the dimensions of our universe and at least 7 outside of those dimensions). Therefore He is extradimensional, and probably not composed of ordinary matter, but this does not make Him non-existent. The Bible is also clear that God exists both within our universe and outside of it.
#10: God has never contacted me. He must not exist.

We would never notice God: This is not an evidence against God, but rather describes the lack of sense in praying to a God who stands above time.

However, the Christian God exists both within and outside of our single dimension of time. Existing in at least two dimensions of time, God is not restricted to always following our time line, but can, through His second dimension of time, spend as much time as He likes at any point on our time line. This concept is stated biblically in 2 Peter. Therefore, if 100 million people are praying to Him simultaneously, He is able to stay at that point in our time line for as long as necessary to hear and respond to their prayers.
#11: God cannot be involved in our universe if He stands above our time dimension

If God stands above time and created time and space he can not be the first link in a time dependent chain of events. Rather he would affect every step in all chains, and we would only see God in the laws of physics (Davies, 1983, chapter 4). This God is an unnecessary entity to describe the world and should be removed with Occam's razor.

Again, the author fails to recognize the Christian God exists in at least two dimensions of time, as such He is not bound by the chains of events tied to our single dimension of time. Davies book is out of date and he lacks understanding of Christian doctrine. His later comments reflect a different understanding of the universe and its design:

* "There is for me powerful evidence that there is something going on behind it all....It seems as though somebody has fine-tuned nature's numbers to make the Universe....The impression of design is overwhelming".
* "The laws [of physics] ... seem to be the product of exceedingly ingenious design... The universe must have a purpose".

#12: If God existed, prayer would have already changed the world into the best possible world.

If somebody would pray to God and God would listen, the laws would change to achieve the desired result. Thus the world would be different and the prayer would never have been said. Besides God would already (in an "above time" sense of view) know that you would pray, and already have changed the world. Prayers would be totally meaningless. We would already live in the best world possible, and any prayer would be to doubt the wisdom of God.

Again, a complete lack of understanding of the Christian reason for prayer. Prayer is communication with God. Communication is a two way conversation, not a monologue of telling God what to do. If Christians were perfect, every prayer would be answered because we would always be within the will of God. However, as most people are well aware, Christians are not perfect and often pray against God's will. God will not do anything against His will and therefore will not grant our selfish requests. I could pray that God would let me win the lottery (if I played it). However, God knows that I would become greedy, buy all kinds of computers and gadgets, and ignore Him. It is in my best interest that I remain middle class (it might even be better for my spiritual life if I become poor - I hope not!). The main problem is that we are stupid and selfish creatures, and don't really know what is best for us. However, God, being omniscient, does know what is best for us. Therefore, the purpose of prayer is not to tell God what to do, but to be conformed to the will of God (i.e., listen to Him).
#13: Only things that can be sensed with the five senses are meaningful to discus. Therefore, all discussion about God is meaningless.

Logical positivism is based upon the verification principle, which states that for a statement to be meaningful, it has to be either true by definition or verifiable by one or more of the five senses. This means that all discussion about God should be considered meaningless. However, the verification principle itself fails its own test, since it cannot be verified by any of the five senses. It is a self-refuting principle, and, therefore, logically flawed.
Nobody really believes in God

Love Your God With All Your Mind: The Role of Reason in the Life of the SoulMany atheists tend to stereotype Christians as stupid, uneducated people. However, I personally know dozens of scientists who are Christians, and not only believe in God, but can rationally present evidence for His existence. In our department at the Research Institute of Cedars-Sinai Medical Center we have no atheists - although we have one agnostic. All the other people - 4 M.D.'s, 2 Ph.D.'s, 3 R.N.'s, and the others, with B.S.'s or M.S.'s - are theistic. Christianity specifically calls people to use their brains. As Robert Griffiths (Heinemann prize in mathematical physics) stated:

"If we need an atheist for a debate, I go to the philosophy department. The physics department isn't much use."

It is the atheist who now denies the implications of modern cosmology and physics because they imply the existence of a Creator. Those who believe the Big Bang correctly describes the origin of the universe, must admit that the universe had a beginning in finite time and space. Did it just pop into existence on its own? Did it just happen to have exactly the right physical laws and constants required for life? It is the atheist who must believe in miracles to explain our existence. Therefore, John Gribbin, an atheist physicist has stated:

"The biggest problem with the Big Bang theory of the origin of the universe is philosophical - perhaps even theological - what was there before the bang?"

The primary objection to the Big Bang and its implications is this "God problem," not because of a lack of scientific evidence. Geoffrey Burbidge, astronomer from U.C. San Diego has recognized the implications of the 1992 COBE satellite discoveries, when he complained that his fellow astronomers were rushing off to join, "the First Church of Christ of the Big Bang."

The fact that the evidence in support of the existence of God has increased in recent years is also a problem. According to atheists, science is supposed to get rid of the gaps, so that there is no longer any room for a "god of the gaps." This evidence has convinced some famous atheists to become deists (e.g., Antony Flew) or even Christians (e.g., Frank Tipler).
If God exists, how can we know what religion properly describes Him?

If God is so mysterious, how can we know anything about him? Through the Bible? How do we know that the Bible and not the Koran or the Vedha books, for example, are the words of God? (or the Bible if you believe in any of the other two books). Considering the cruelties that have been made in the name of God, how do we know that not all religions are made by Satan?

The God of the Koran and Hindu Vedas are Gods restricted to the time and space dimensions of this universe and, therefore, are logically impossible (check out some of your own proofs). In addition, most of these books contain scientific absurdities. All the so-called holy books base their claim of authority on the basis of fulfilled prophecy. Most of these prophecies are either vague or conditional, making them essentially untestable. The highest percentage of prophecy fulfillment, other than the Bible is 50%, with many other prophecies proven to be false. In contrast, the Bible names people, places and dates in remarkable detail, with 2,000 of the nearly 2,500 prophecies already fulfilled, and none provably false. The remaining prophecies are reserved for the end-times, which have yet to have happened.

I absolutely agree with atheists who say that many atrocious things have been done in the name of God, even in the name of Christianity. However, these atrocities were not perpetrated by God, but by evil human beings. Remember the words of Jesus:

"Many will say to Me on that day, 'Lord, Lord, did we not prophesy in Your name, and in Your name cast out demons, and in Your name perform many miracles?' "And then I will declare to them, 'I never knew you; DEPART FROM ME, YOU WHO PRACTICE LAWLESSNESS.'" (Matthew 7:22-23)

Not all who claim the name of Jesus are actually His disciples. My guess is that in even the best of Christian churches only about half of the people truly are Christians. Christianity should be judged on the basis of what Jesus said and did, not on the basis of what people do who merely claim to be Christians.
