Do you really want to understand? Are you really intersted in the truth? Then do research evolution. Find out what it really is, not just what creationists tell you. I guarantee you'll come to a new understanding of it and see that it is very well supported.
Basically it's small mutations adding up over a large period of time. The mutations that are most useful will survive best, and increase in the gene pool. Part of evolution is random (mutation): part of it is not (selection or survival based on environment, or what gets passed on most successfully in reproduction).
Let me just point out here that mutation does not necessarily mean bad, but just CHANGE. It's just a change that occurs-that's all. Sometimes the change is detrimental, sometimes it's not, sometimes it's actually beneficial. Think about it: why must mutation always be detrimental? It's just a CHANGE. That's all. It may be beneficial or not. Natural selection determines what mutations multiply in the gene pool and which do not.
Evolution is the best supported theory in science. And by the way, a theory in technical or scientific terms means a structure of facts which form an explanation of something. If it's not well supported by a lot of evidence, it will not become a theory. We have the theory of gravity and the theory of relativity for example. See http://www.talkorigins.org/faqs/evolution-fact.html "Evolution is a Fact and a Theory" for more on this.
The fossil record is rich with evidence that evolution has in fact happened, whether people want to believe it or not. The whole field of biology wouldn't make sense without evolution. You can thank the field of evolution for our medical knowledge. Every field of science supports evolution.
You've been duped by people with an agenda to keep people under their control. Please, research this from objective, unbiased sources.
Also, keep in mind that accepting evolution does not mean you must give up your belief in god. I've believed in god most of my life and never questioned evolution. Who's to say god didn't use evolution? Why must they be mutually exclusive?
