I did. I said if a watch has a maker, and is less complex that nature, then why is it believing in fairy tales to believe that the universe had a maker?
I'll put this forward too, and atheists can feel free to disagree with me:
There is very little that would "prove" to an atheist that God exists other than Him appearing in the sky and saying "Ok guys, see? Is this enough proof for you?"
I'll illustrate it this way: As an atheist, suspend your disbelief for a second and imagine this. Let's say that the rapture ACTUALLY HAPPENS. Millions of people suddenly vanish from earth. Do you actually think that the majority of humans would actually believe that God came and took His people? Or would there be more "rational" explanations for the vanishing? There would be discussion of aliens. There would be discussion about government programs and technology that we didn't know existed. There would be hundreds, if not thousands of theories as to how it happened.
And this isn't new. Again, suspend your disbelief, and imagine being alive while Jesus was on earth. He performed hundreds of signs that were supernatural. Did that cause everyone to believe in Him? No. MOST people did NOT believe He was the Son of God. And many wouldn't today. There could be an outright miracle performed today, and it still would have a more "rational" explanation as to how it happened. But God doesn't force anyone to believe. That is why the essential quality that has to be there is faith. Atheists hate the term "faith" because it implies believing with no evidence. But this isn't the case. Logically I believe that every peice of technology has a maker. I don't see why it is so illogical to infer that the rest does as well. Faith is needed to attribute it to God. Faith takes the proof that is available and says "I believe that it must be God that is responsible".
And this isn't unique to Christians. We talked about Francis Collins either on this thread or another like this. He is not a Christian. But through all of his research in the area of DNA he infers that there MUST be a designer. He is a theistic evolutionist. He believes in science 100%. But would you accuse him of believing in some type of fairy tale because he has concluded that complex systems of information cannot have come about by accidental processes and chance? No. More respect is given to him because of his background and wealth of knowledge.
I can't help but think that no evidence would be enough for a solid athiest to believe in God. Atheists like to say that there is not enough proof. I could imagine some of the atheists on this board being present at some of the acts performed by the prophets in the Old Testament, and trying to find the reason behind what happened. Take the account where Elijah called down fire from heaven to "eat up" the water drentched wood and meat on the alter. Would not a "scientific mind" have a reasonable explanation for that event to show that it wasn't actually God, but was instead some sort of weather or other type of phenomenon?
Really, what proof would be enough proof other than God appearing in the sky? And would even THAT be enough proof? Jesus said and demonstrated that He was the exact image of God. However, the proofs that he showed were not enough for most of the people.
