Intelligent design

Intelligent design is the proposition that certain features of the universe and of living things are best explained by an intelligent cause, not an undirected process such as natural selection. It is a contemporary adaptation of the traditional teleological argument for the existence of God.

Deniers of intelligent design often cite experiments which they believe demonstrate that life can arise from random occurrences. One such experiment was conducted by Nobel laureate Harold Urey and his protégé Stanley Miller, and you can read about it @

The Miller-Urey experiment was itself based upon an experimental design: the initial composition of the materials, the conditions of temperature and pressure, and the type and amount of energy introduced into the mixture were all part of an experimental design intended to mimic conditions on ancient Earth.

Duh! An experimental design is an example of intelligent design. How can one disprove a concept by relying on that very concept in his experiment?

And can someone please explain to me how this entire universe came about in an instant (the so-called Big Bang)? All experiments which attempt to answer that question also are examples of intelligent design, aren't they?
