The simplicity fallacy

Just listened to last week's Unbelievable show on "Can atheists believe in human rights?"

The basic argument put forward by the Christian guest on the show was that humans would have no 'human rights' if there was no creator God to give those rights to people. The atheist guest on the show more or less conceded this point and claimed that human rights are a human construct, and are not really inherent.

The details of the debate are largely irrelevant to the point I want to make here. But it struck me, while listening to this podcast, that I've heard the same basic form of argument for God in debates (both on Unbelievable and elsewhere) many times over.

The basic, underlying, argument is this:

The [thing we are talking about] is much simpler to explain in a universe created by a God than it would be in a universe not created by a God. Therefore we can conclude there is a God.

The same argument has been made concerning human rights, morality, reason, science, etc., etc.

Its just not a very good argument. The fundamental flaw in this argument lies in its implied appeal to Occam's Razor. Two options are presented, one is made to look simple, one is made to look complex, thus the simpler one is the preferred (by which it is assumed we mean 'true') option.

I agree, human rights would be much easier to justify if they were granted by a higher power, relative to if they were not. But the two opposing sides in this situation are not:

1. Complex justification of human rights with no granting authority, vs.
2. Simple justification of human rights with a granting authority, 

but rather:

1. Complex justification of human rights with no granting authority, vs.
2. Simple justification of human rights with a granting authority PLUS very complex justification of the existence of the infinitely powerful granting authority.

Given that the argument itself is usually being framed as an attempt to prove the existence of God, it usually overlooks all the circular reasoning and begging the question that is going on here. The whole thing presupposes that God can do anything, which of course makes anything that God can do into a simple task. But you can't have that presupposition when trying to justify the existence of God.

God is anything but 'simple'. Any argument suggesting that something would be 'simpler' by assuming God is fallacious.
