You should post this on the Biology & Genetics subforum. This is the wrong place.I do not no where to begin so I will just ask. I am having trouble understanding the process of evolution, especially concerning what makes it happen. What is evolution's origin? What makes it happen?

It involves a repeating process like reproduction (with variations), and a selection force, like the environment.
The living thing that happens to be better suited to the environment is able to make more copies of itself, thus influencing successive generations.
The operative entity in evolution is the gene. It has no intentions, but becomes more or less prolific in proportion to the suitability of the machine it builds to reproduce itself in it's environment, which includes both the Earth, the body, and other genes.

There is no origin and nothing 'makes it happen'.
What exactly don't you understand about the process ?
That you have posted this in the religion forum, that you have already mentioned creationism, and the nature of your avatar makes us highly suspicious of your motives. :bugeye: I doubt that you really want to learn any science but instead are looking to start the usual evolution-creation crap fest.
If I’m wrong and your intentions are genuine, then you would do well to go to a library and check out a beginner’s book on evolutionary theory. Asking internet forum participants to explain evolution rarely results in satisfactory answers and nearly always degenerates into the aforementioned crap fest full of misinformation.
Answer:
That's the amazing thing, it doesn't act at all. A gene never adapts itself. Sometimes, when it gets copied, it gets copied inaccurately, and those changes affect how often it gets copied in the future, due to the variability of the survival of the living machine that comes from it.
Where the gene comes from is a bit of a mystery, scientists think it may have come from RNA based life forms. The study of this is called abiogenesis.
It is proposed that the early Earth, being lifeless, accumulated organic chemistry in it's oceans, which, under deep sea pressures and volcanic heat, was saturated with dissolved minerals. Laboratory testing reveals that the chemical precursors to life are formed in conditions like the early Earth- lightning, ammonia in the atmosphere, water.
Due to the mere shape of some molecules, they can influence the kinds of combinations that occur within a system. We know this kind of action as a catalyst. A molecule made of more than one component can hold other examples of it's constituent components in place so that they react much more readily than if they depended on running into each other at random. When outcome is a copy of itself, it is known as a self-catalyzing reaction.
The copy then makes a copy, and the reaction grows exponentially. Each time a copy comes together, probably floating in the ocean, just by bumping into the required molecules, there is the possibility of error. Perhaps one of these errors is better at making copies of itself. That version becomes the most common. Given enough diversity, these molecules could find a parasitic strategy on other types, forming a situation that we know of as an "arms race". The more complex a molecule, the more possibility of errors, and thus the more probability that it will form a variation that can exploit all available resources, including others like itself, more effectively.
The outcome of this process were single celled structures that exploited the sun's energy to power themselves and copied themselves by dividing.
How those became you is the subject of evolution.
Warrior61:
Are you interested in evolution or the origins of life? Because the two things are quite separate questions.
What is evolution's origin? Not the theory/concept/idea of evolution.
How something as great as evolution can act and have no cause and how life has no origin. Enlighten me?
But how the earth and its water and lighting etc. got here is a mystery?
What is evolution's origin? Not the theory/concept/idea of evolution.
