As for evolving eyes, a scientist explained one predominant theory well.
For a vision receptor (rods and cones in the retina for example) you need many proteins working together in a precise order for it to work. This happening at once is highly unlikely. However, if an organism has several subsystems, like a flagellum or cilia, that have a certain smaller number of proteins working together and other smaller systems like that, it's not a big stretch for them to randomly co-opt. By chance two sets of proteins that are already ordered up can join to form the long chain for a more complex component like parts of an eye to form.
Even though eyes are amazing, I still don't see how that's more of a stretch than "God put dinosaur bones under the earth just to fool us into thinking the Earth's older than 6,000 years old or some shit." See, I may be as ignorant of the other side as you are of evolution, but I don't give a damn so stfu.
