My argument for atheism +

[snowtracks]

Not if thoughts come from brains.  

Just exactly what was that first thought that originated from a brain that was formed without any prior thought?

These were your rules...you insisted.  

the cause is always greater than the effect since it initiates the transaction.

I want you to know that I absolutely agree with you.  Thoughts originating from brains is the greatest thing that ever happened..though I probably would say that, as a thought originating from a brain.  Still, I don't think that the application of the snowtracks principle is having the intended effect.  It might need careful rephrasing.
