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

[RoadRunner79]

That is a lot of claims for someone who was shifting the burden of proof just a few minutes ago (out of context; I may also add).
Now it is my turn to ask why?  What evidence or reason do you give for these claims?

Again sorry, but this is the same dodge everyone of every religion gives. 

We are finite, sorry you don't like that. I am trying to help you escape your fantasy. 

13.8 year old universe and you'd have me believe some old and unscientific book of myth explains shit?

Everything has a shelf life all the way down to atoms. Atoms cannot act like an entire in tact functioning brain. Break down the functioning highway into unusable pieces it will not be in tact. If you really think you survive your death we should expect to see neutral experiments where you could decapitate a human head, re attach it and have it function as if nothing happened. Same with our planet, all it would take to kill our planet and all life on it is a meteor or commit bigger than what killed the dinosaurs, like the commit that hit Jupiter a few years back. 

The sun as well has finite fuel and it will burn out, collapse or expand and eventually die. 

If you already reject rightfully the afterlife myths of other religions, even the pre life reincarnation and post life reincarnation myths of even Hinduism and Buddhism, as well as the afterlife myths of Jews and Muslims and the Ancient Egyptians then you should have no problem ditching even your own position. 

You are scared of being finite. No I don't mean death, just not being around as a consciousness forever. I am saying there is nothing to be afraid of about not existing just like you are not afraid of what it was like 5 million years ago.

What dodge?  I asked a question based on your claims... Which seem little more than physical things are finite..... I would tend to agree.  They have a beginning and an end.  This would also apply to a physical cosmos correct?  Now I would disagree somewhat with the assumption that there could not be something unlike what we have seen (and basing it only on that).  But I have heard a philosophical argument, that physical things are necessarily bound and therefore also finite.  

There was also a number of other claims in your post, that you didn't even touch on.... the question still remains as to why (your reasons or evidence for being so).

And would you please quit projecting your assumptions onto me... you are not very good at it.
