Wow, the Watchmaker Theory. Glad to see another delusionist here to keep me company.
Ok, as to the OP.
- Things are complex
No, things are not complex. “Complex” relies on a standard of simplicity that just does not exist beyond the binary. Once a standard of higher than binary simplicity is established to measure complexity against, complexity itself raises the norm. The short answer is, there is always something more complex and, until Moore’s Law becomes obsolete there always will be.
- The more complex things are, the more likely they are to be created more or less whole rather than through incremental improvements
Not exactly. As things grow more complex the boundries for complexity expand (see position number 1). Once a certain level is obtained hindsight reveals that which was once intricate is now quite pedestrian and mundane. The formerly Divine becomes strikingly mortal and the Amazing Magic from days past are no more than mere parlor tricks to pass time with the kiddies. Incremental though the steps may seem, the fact that they do keep marching on alludes to the time when that which is complex today will seem simple and the steps in their creation will be quite obvious.
- There are many things so amazingly complex that we see no likely way they could have come into bing incrementally.
Again refer to the answer to item #2. What we saw 1000 years ago versus what we see now is exponentially different. What we may see in another 1000 years in accordance with Moore’s law may be something that we are currently unable to even imagine.
Keeping in mind that Moore’s law only applies to technology. Within evolution there are peaks and plateaus, sometimes even valleys. The incline varies from species to species and individual to individual but the fact remains that it is an incline.
However, yes I am also a delusional follower of the Tinkerer. Although I think you are on the right track, you are needlessly confounding things. Keep it simple. Yes, complexity can arise from simplicity, this is a cornerstone of evolution. Other wise we would all still be paramecium. So the arguement from the origin of God is lame.
If simple organisms can, through tried and true methods, over enough time and generations evolve into higher organisms then these higher organisms can be said to come from the simple ones. The complexity of the Watchmaker does not have to be that much greater than our own, it can in fact be much simpler. And if a origin of the Watchmaker is revealed, it is also possible that the Originator was simpler still, possibly below the point of being a singularity (hey, infinity goes along just fine in one direction, why not in the other?).
The arguement from no universe before universe has a similar hole. Only the definition of universe constrains the boundries of this one. That which was before could have been, by definition, not a universe. It could have been dimentionally different and thus, reality as we know it truly might not have existed before our own.
The arguement from an advanced alien species is also constrained. The advanced alien is bound by it’s own definition of itself. Even if it is exponentially further along the evolutionary ladder, it still limits itself against its potential. Any being that could corporally interact with us sets its limits thusly.
Anyway, that is how I would answer the OP and help patch up the arguements. Keep it simple, seek further simplicity. But don’t expect me to look for scientific (or even logical) proof of God. As I maintain my position that science and God, while not mutually exclusive, are like studying apples to prove oranges exist. The Watchmaker is blind in our standards because He does not need sight. This does not mean we are blind, just that we cannot see where He sees. Science provides an interesting study of His tools and techniques, but can never study Him.
