"But nature is so complex..."

I've heard this one a lot. The natural world is really complex, and that means that there must be a designer. This is simply not true.

Natural selection gives the illusion that the natural world is complex. Let's look here.

We have bees adapting to the environment by getting their "waggle dance." We have roses getting protection with their thorns. The fossil record shows that they did not have this a few million years ago. This was recent. Plants and animals evolve, and adapt to their environment. The advantageous "design" (for lack of a better word) gets spread and the obsolete adaptations die out. This is how adaptation works. It is not fair to say that nature is "so complex." It is, in the sense that it has to be, or most of it would die out.

Also, a fair point would be that if nature was designed, it must have been made by a poor designer. We breath and eat out of the same tube. Our bones are easily broken. If we drink too much, our body reacts in a negative way. We have allergies, and while it works, it works poorly for us. We are just badly designed in general.

So no, we are not complex because we are complex.
