Evolution is the most correct theory that explains the origins of the divisity of life.
Evolution by natural selection has been observed in several parts of the world (within our lifetimes), its been shown in the lab, the fossil record is increasinly more comprehensive and the complete sillyness and chaos of our bodies point to evolution and not a creator. The fact that the photo receptors in our eyes face backwards, that koala pouches face downwards despite the fact that they live in trees etc points to animals that both slowly and rapidly mutated (and were selected as being advantaged by natural selection) and such mutations were fixed after the fact because they weren't neccesarily very elegant solutions (something that would cause a designer to go back to the drawing board). Note Koalas are evolved from Wombats. Which burrow underground, hence why the pouch faces backwards, so their young don't get dirty etc. The explanation of why the Koala is like it is only makes sense when evolution is applied.
If the designer did design us all he's either very cruel, or actually very very stupid.
Thankfully the more elegant solution is the one with the evidence.
