One of the main pieces of evidence for creationism is irreducible complexity, where a system is made of multiple parts, each of which are important and without them the whole system will stop working. Is it really possible for evolution, a process where everything happens by chance, to create something like this?
The argument is this: Because evolution is a a process that gradually changed organisms little by little to better their chances of survival, it can’t produce such a complex structure in a short time. It can slowly modify them, but they need to come from somewhere first.
A simple example is a mousetrap. It has 5 main parts that each have an important function the trap can’t do without.
Without a spring, the hammer will just flop around; Without a catch, nothing will trigger the contraption. Because of this, the system will be useless until its building process is completed.
In evolution, something like this wouldn’t be possible. Not only can’t a complex system just suddenly come into being, but because of the nature of evolution, useless small parts can’t be added bit by bit. This can only be explained with that there’s a higher power somewhere that designed it.
