I can understand why some people would have a problem with the evolution of eyeballs though, don't you subbie?
Actually eyes are pretty easy to understand since we can see all the various steps and types in use today, from the most primitive, limited functionality to the most advanced such as those on squid and octopus.
There are even critters that have multiple types of eyes and use all of them, the box-jellyfish being a great example.
Remember that even basic light sensitivity offered an advantage long before there we ANY animals. The earlies photosensitive plants would have had it. We can see it even today in plants. When the early whatever, the earliest animal type critter came along, light sensitivity too would have been useful. And those critters with better sensitivity would be more likely to eat an less likely to get eaten.
For me the most convincing part is that when we look at eyes, what we find really is "just good enough to get by", we can see all the intermediate steps, see examples of many different solutions to the issue of sight, and understand why particular features would have given the possessor a slight advantage and so likely to have been seleted for.
