Argument from poor design
The Dysteleological argument, or argument from poor design, is an argument against the existence of God - specifically a competent creator God.
"Something is wrong here. War, disease, death, destruction, hunger, filth, poverty, torture, crime, corruption, and the Ice Capades. Something is definitely wrong. This is not good work. If this is the best God can do, I am not impressed. Results like these do not belong on the résumé of a Supreme Being. This is the kind of shit you'd expect from an office temp with a bad attitude. And just between you and me, in any decently-run universe, this guy would've been out on his all-powerful ass a long time ago."
"[Regarding living things,] How hostile and destructive to each other! How insufficient all of them for their own happiness! How contemptible or odious to the spectator! The whole presents nothing but the idea of a blind Nature, impregnated by a great vivifying principle, and pouring forth from her lap, without discernment or parental care, her maimed and abortive children!"
- — Philo in Dialogues Concerning Natural Religion
The implication of the argument is that God is either incompetent, malevolent or non-existent.
The argument typically goes as follows:
- An omnipotent, omniscient and omnibenevolent God would create organisms with an optimal design.
- Organisms, including humans, have features that are suboptimal.
- Therefore, God either did not create these organisms or is not omnipotent, omniscient and omnibenevolent.
Some of the suboptimal features often touted includes:
- The eye (including the human eye, as the retina is backwards -- among other imperfections).
- The Laryngeal nerve (seen most spectacularly in the giraffe with a multiple metre detour to reach a displacement of mere centimetres).
Speaking of the traditional conception of God, Stendhal wrote: 
- "The only excuse for God is that He does not exist."
Biblical God agrees it was a mistake
Genesis 6:5-6 states:
- "Then the Lord saw that the wickedness of man was great in the earth, and that every intent of the thoughts of his heart was only evil continually. And the Lord was sorry that He had made man on the earth, and He was grieved in His heart."
Emotional expression and admission of error also incompatible with God's supposed inerrancy and unchanging nature.
Earth and humans are not distinct
- Main Article: Earth the center of the universe
If humans or the Earth were designed by God and are a significant part of creation, we might expect them to be distinct in some tangible way. However, it seems odd that there are many other similar planets (as discovered by Galileo) and humans are animals similar to all the others (as confirmed by Evolutionary theory). Since the humans and Earth are not distinct from the rest of creation, they are not specially privileged or significant. Therefore, claims to the contrary in holy scriptures are false.
Most of the universe is hostile to life
It look billions of years for life to emerge in the universe. Also, most of the universe is uninhabitable and hostile to life.
"So if the purpose of the universe was to create humans then the cosmos was embarrassingly inefficient about it."
