1. The universe exists
2. The fine tuning of the universe
3. The rational intelligibility of the universe
4. The existence of moral absolutes
You can't put the nail in the coffin with this kind of thing. You need to understand that first and foremost. But here are a couple of ideas for you:
1) Yes. The universe does exist. But this is like saying 2 + 5 = 7 because 2 exists, where 7 is the universe. We can't argue for what came "before" the universe because it's out of context. Space and Time didn't exist before the universe existed, and that single item (space-time) is on what we base our entire model of theory. Stephen Hawking's "Model Dependent Realism", explained in his book, The Grand Design
, does a great job of this.
2) The universe is not fine-tuned. This is an illusion...a result. If you apply a set of rules to something, it will naturally develop its own form of order. The Game of Life is a great depiction of this. Using a simple set of rules, you can turn pixels on the screen into what appear to not only be ordered clumps of "cells", but actually living "creatures". And that's what happened with the Big Bang. Matter and anti-matter SHOULD have annihilated each other, but a little matter (a lot of matter, actually...the universe we see and touch) escaped. Matter has a set of rules assigned to it. But these rules aren't arbitrary. They're properties. And the properties of matter formed the universe. It seems ordered only because it follows a set of rules.
3) If the universe was intelligible, we wouldn't have these discussions in the first place.
4) There are absolutely no moral absolutes. Why? Well, we define morality only by defining immorality
. The post on my website talks about this. But the truth is as follows: moral is that which is not immoral. The authors of the Bible know this. They put it in the story of Genesis. How did Adam and Eve know what was moral? They were told what was immoral
. And by that definition (the very same definition given by the Bible), we can allow Christians to give us an action that is "absolutely immoral". And because we are knowledgeable, we can instantly name a place on the planet in which that action is not only NOT considered immoral, but it is considered inherently moral, appeasing to the gods (or God), and has allowed the culture to survive for thousands of years.
