I understand what I was forced to learn about evolution in school but the teachers could never answer basic questions without doing some crazy dance. For instance what about the stomach? How did a stomach evolve to hold acid? or the eye needs all of its parts to function so how does anyone part form individually.

Both of these things are not exclusive to multi-celled organisms, only the level of sophistication.
Single celled organisms have Lysosomes which contains digestive enzymes that without the ability to localize and contain them would dissolve the cell from the inside out.
Not all animals have eyes, not all cells have ocular organelles, however evolutionary theory explains to us that when different types of cells began to form symbiotic colonies, different cells began to specialize performing different tasks, this is how all of the sensory receptors eventually came about. There's no song and dance about it. You've simply had shitty teachers who couldn't think outside the box (Shitty curriculum)

Evolution hinges or these mutations but there are very few beneficial mutations that I am aware of although I have heard some argue that sickle cell is a beneficial mutation (LOL) . Mutations would have to be passed to the offspring as well which usually does not happen and you have other things to consider like the pleiotropic effect which means one system affected by a mutation does not happen in isolation but usually effects other systems of the organism.

Natural selection. I can't simplify it more.

If someone could show me beneficial mutations (and no I dont mean moths during the industrial revolution that have already been shown to in fact too not be an example of this) then perhaps I would change my views.

Do you know how many times they've needed to re-design penicillin since it's invention because the bacteria continues to mutate and adapt?
