We understand and believe you...except, and this is a big one, the effort behind the insertion of ID into the education system is claiming that ID has nothing to do with the supernatural. However if you separate the possible causes in two camps, those that occur naturally such as evolution and those that do not occur naturally the natural causes can be rendered down to non-intelligent designers. This leaves only the non-natural causes. (Remember we are dealing with something that can directly manipulate features on Earth organisms, poke around in DNA sequences and the like)
If you posit aliens as non-natural causes as ID is wont to do, then the options for their existence are - they were created by natural processes, they were created by non-natural causes or they created themselves.
We can dismiss the first point out of hand because that is what ID is trying to disprove. The second point just brings us back to the same question - how were the aliens that created the aliens that created us created? Eventually you have to stop the circle of aliens creating aliens and move on to something that created itself. (You can't use the argument that they have always existed because that could also be applied to natural causes). If some alien race was able to create itself, I would say they have pretty much the same capabilities as the supernatural supposedly does. All in all it looks like ID can be boiled down to supernatural causes.
But ... but ... it's science! It's gotta be science! It's science!!!! [Scream, rant, pound table, sob, faint]
Creationists invariably fade to black when confronted with an infinite regress.
I would agree that ID requires some sort of supernatural cause. Personally, I believe that cause is the God of the Bible. Others on the ID side would argue that the 'designer' is not known.
The evolutionist has a similar problem. Just as some IDers claim they don't know the identity of the 'designer', the evolutionists does not even attempt to explain the origin of life.
If the evolutionists cannot identify the force behind the origination of life, it is unreasonable to expect the non-Christian IDer to identify the 'designer'.
The evolutionist who claims the origin of life has nothing to do with evolution is being at least as disingenuous as any IDer who claims that the designer is unknown.
Based on the comments of some of the evolutionists on these threads, some evolutionists concede that the origin of life could have a supernatural cause. Is the belief in the existence of an intelligent designer really any different?
