Finger...not sure that I can add much more to what chakka has already said, but here's my view.
1) I love nature.Im happiest when Im by the sea or in the country.I dont understand why this should mean that there must be a God.Nature is beatiful in its own right.However there is a flip side to this.Do we admire nature when theres an earthquake, volcano eruption or tsunami, that kills thousands? Do we see God then or do we see the destructive power of nature?
2)Just as there are atheists who convert to religion, there are religionists who convert to atheism (and ive known quiet a lot myself).Here's one minister who did just that..

Again, it cuts two ways.
3)I cant really add to what chakka has already said on this one.
To my mind, having a belief in God throws up many more question than does atheism. If you have this belief in God, then exactly which God? Im sure Finger, that you have no belief in Odin or Thor and yet people once did.Why is your belief any different from theirs? If we look at the present day, many people believe in Brahma, Vishnu and Shiva.Why dont you accept these gods?
After spending years searching (and researching) the only logical and viable world view seems to be atheism.
