Evolution not observed?
The idea that evolution has not been observed is false. It has been observed directly and indirectly.
I have been reading Richard Dawkins' "The Greatest Show on Earth" and he tells us about a species of Lizards, whose primary diet was insects, that changed over a few decades to be able to eat vegetables. It had stronger bones in its jaws, a different head size, and some other features that escape me at the moment. Then, he talked about an experiment with bacteria in which the bacteria was eating a glucose rich...thing (I forget what was happening, help me out here) but one of the test tubes of bacteria evolved to eat another one of the substances prestent along with glucose, encouraging a large surge in bacterial population.
Evolution has also been indirectly observed. Like the theory of continental drift. Who here has EVER seen the continents move? Anyone? Yet we teach that the continents used to be together? How did they move? Earthquakes? There are earthquakes every year for several years, but the continents are still exactly where they've been for decades....wow that sounded like something a creationist would argue.
The fossils show that life was different than it is now. Something happened to the animals. What happened? They evolved. Why did they evolve? Natural selection drove them to.
Our job on this Earth, is to take care of each other. Something that we have ultimately failed at doing, hence why we are so miserable.
