Theists: What is the most compelling argument you have heard for Atheism?

[SteveII]

You are right that something is confused. You don't have proof of your statement above (bolded so you can't miss it). So, it is your opinion. It is as simple as that. 

A quick reminder of definitions:
Evidence refers to pieces of information or facts that help us establish the truth of something. Proof is a conclusion about the truth of something after analyzing the evidence. Evidence is suggestive of a conclusion. Proof is concrete and conclusive. Proof can have different thresholds. Anywhere from more likely than not (preponderance of the evidence), to beyond a reasonable doubt, to absolute. These are all arrived at by considering evidence.

So, to say that I have no evidence is simply wrong. What you mean is that in your opinion, it is not proof. That's fine, I don't care what your opinion is.

The evidence that I believe that supports my belief (another opinion) is below:

1. Person of Jesus is compelling.
2. The NT describes actual events including the miracles, life, death and resurrection of Jesus. 
3. God works in people's lives today--changing people on the inside as well as the occurrence of miracles.
4. The natural theology arguments:
a. God is the best explanation why anything at all exists.
b. God is the best explanation of the origin of the universe.
c. God is the best explanation of the fine-tuning of the universe for intelligent life.
d. God is the best explanation of intentional states of consciousness.
e. God is the best explanation of objective moral values and duties.

Since you cannot 'prove' that any of these are falsely held beliefs, my conclusion (opinion) that God exists is rationale.  The amount of evidence meets my personal threshold for proof that God exists.

Holy giant wall of naked assertions Batman!

1. To you yea, because you like the claim, still not evidence, still a naked assertion.
2. Every religion has writing and or events they claim to be "miracles". You don't own the patent on that word.
3. No, you like the idea, and again so what, other people think their superstitions work for them.
4. Nope, theology is an apology nothing more. It is a sales pitch, nothing more.
5. Says you, so what, other people say that about other gods of other religions.
6. Again so what, there are tons of creator myths in our species history.
7. "fine tuning", yea like the fact humans can choke on food because we breath and eat with the same tube.
8. Again, see 5.
9. And Buddhists and Hindus and Jews and Muslims also claim their religions are the core of human morality. 

Not making any arguments here I have not seen from other religions.

I'm curious of two things about you: 1) how old are you and 2) why do you participate in discussions like this one?
