The vast complexity of living things proves that God exists (proof 1)

[Doubting Thomas]

Or a fallen and cursed creation as the result of the sin of Adam and Eve.

So you're saying that everyone's bodies were perfect, but the second Adam & Eve ate the fruit then our bodies got all fucked up?

First of all, how do you know it was God that created the entire universe and not some other magical, powerful being?

And who or what created God?

When an atheist proposes God as a rebuttal, the atheist has disproved himself.

Please show where I proposed a god as a rebuttal? All I'm asking is how do you know that the creator of the universe is Yahweh and not the Flying Spaghetti Monster, as a hypothetical? How do you know it wasn't aliens from a parallel universe who created life on earth? How do you know that the entire universe isn't some strange science experiment in a jar in some huge, massive laboratory in some mega-universe?

I can ask questions about gods and still be an atheist just like I can ask questions about flowers without being a botanist.

And again, if you're going to assert intelligent design, who or what designed the designer?

Atheistic origin science has completely failed to explain the universe and life.

As has Christianity. At least with science, "I don't know" is a valid answer and leads to more discovery. All Christianity has is "Goddidit, so shut up and keep praying" which stifles scientific discovery.
