You see, this is the point you guys miss; that in every experiment, the ludicrous nature of "chance" creating all of life, is disregarded in reality by the fact that it is removed by the fact that someone has intended an experiment and sets it up.
Now if a computer program, created by itself, and a computer created by itself, and EVERYTHING, on it's own, came to pass, that would be remarkabe. It would also be the logical EQUIVALENT to random natural evolution with no designer. So show me that instance and I will believe it happened on it's own.
This is, of course, off topic here but I don't think it should be ignored.
You are, in a way, moving the goalposts now. We are talking about mutations and biological evolution. The discussion is about what is wrong with your consideration of the probability of the life forms we see.
However, you are now backing up to, in an analogy with computers, to the origin of the universe. We don't know if the laws which govern the universe had any other possible outcomes nor do we know if we are simple one of many different sets of laws. If some people want to believe that a god set this universe up (built the computer and wrote the software) and let it run to see what would come out (or even knew what would given the initial conditions) there is nothing to disprove that right now. However, that doesn't say anything about the nature of biological evolution.
It may be that the originator knew that, eventually, intelligent life would arise in this universe and in that way it is "intended" and all the mutations and selection are just the process used to get to some intelligent life. Fine,if you want to believe that.
However, there is no hint whatsoever that any tinkering has gone on since the intial formation of the universe. The method used doesn't need any tinkering either. It can produce some very interesting outcomes left to run on it's own. Just as computer programs left to themselves produce very interesting and sometimes surprising outcomes.
The IDists are
not putting forward the idea of an 'unintended' universe so they are trying to go further than the science suggests is correct.
