1. The Problem of Evil
All will be well. And every manner of thing will be well. And all that is not well will be made well.
Evil has no independent existence, it's a temporary aberration, like a ripple in a pond when you throw a stone in it. It will pass.
2. The Omnipotence Paradox
The qualities and virtues of a created thing cannot exceed those of it's creator. If the attributes of a created thing are equal to those of God, then the created thing is God- which makes no sense.
3. Poor Design
How can creation be described as "poorly designed"? Compared to what? Have we ever made anything as simple as an amoeba from scratch in order to compare it to creation?
Strangely designed? Yes, from a human perspective. Behold the platypus
I cannot persuade myself that a beneficent and omnipotent God would have designedly created the Ichneumonidae with the express intention of their feeding within the living bodies of caterpillars or that a cat should play with mice."
I agree with Mr. Darwin. This is not how God created the Earth to be. But that doesn't mean He didn't create it. He didn't create humans to murder one another, but they do. The Fall was not restricted to the human race. As we see with the environmental disasters we have wrought in the short space of half a century, human sin has repercussions that cause echoes and damage throughout the Cosmos.
4. The Unpersuasiveness of God
We can't blame the radio transmitter for our lack of signal if we have destroyed the receiver.
5. Naturalistic Explanations are Superior
If we apply occams razor, "plurality should not be posited without necessity", then a Creator is the simplest explanation. since too many perfect conditions are required for the spontaneous generation of life.
6. Russell's Teapot
We cannot see Black Holes, but we know they exist, and we can see their effects on their surrounds. If we didn't know what a Black Hole was, yet we observed it's accretion disk and gas jet, we might come up with alternative explanations for what we observed (which would be incorrect). The same goes for the effects of the Divine Energies on creation.
7. All Gods Fall
In reality, I guess only time will tell for sure. But 2000 years later, we are still building magnificent Cathedrals. And Judaism (from whence sprang Christianity) traces it's history back to the First Man and Woman.
8. God Needs Nothing
God -the God of the Christians- is a Trinity. A Community of Mutual Love. I don't know whether or not choosing to share community with Creation is a necessity
for the Triune God, but what I do know is that the Father has been Eternally Begetting the Son and is the Source of the Spirit's Eternal Procession. God's Begetting and Community were going on long before Creation, and these are part of His Being.
9. Man and God Comprehension Gulf
God is Transcendent in His Essence and Immanent in His Energies- and both are God.
