An
argument for the
existence of
God. It suggests that the
universe shows evidence of
design, and design requires a
designer, which they
posit is God.
Oddly, the argument is internally self-inconsistent. If something such as humanity is so complex that it needs a designer, then obviously the thing that designed humanity, being more powerful, would be even more complex, and even more in need of a designer. If humanity is unlikely to just come into existence, wouldn't a god be even more unlikely to just exist?
One must remember, however, that even if the argument is shown to have flaws, and thus you find it unconvincing, it does not mean that the thing the argument tries to prove does not exist. (In otherwords, showing the argument from design to be flawed does not say anything about the existence of a god)
