I will prove to you that God exists

The key point is that they are tuned for life to occur.

No, you're simply begging the question. As has been explained countless times, the preponderance of atheism is far higher among scientists, and exponentially higher among elite scientists. I posted objective evidence of this, you ignored it.  

Are you really expecting us to imagine that you, understand what these phenomena evidence, better than the vast majority of elite scientists, among whom atheism and agnosticism is almost universal? Why would we accept a claim so obviously preposterous? 

 Even if the universe "had to be the way it is" for some unknown reason (such as being intentionally caused to exist) its still fine-tuned for life. 

Oh Drew Drew Drew, your whole spiel has used the notion that the universe must be designed, because it could not be "happenstance" that a universe emerged with the properties to allow life to emerge. If no other universe were possible, this would entirely negate that notion, hence @Angrboda asking you how you know those properties can vary. If they can't vary, then not only is this universe emerging not improbable as you keep claiming, it's probability is 1, a nailed on certainty. 

You're offering an objection you admit is only a mere possibility which I seriously doubt you subscribe to.

You are missing the point entirely.
