The Snake

One thing I've never understood is how the snake is able to trick Chava. I know that there are many explanations as to what the snake is, such as a Yetzer Harah. I'm focusing more on the snake, as if it was an actual snake. Adam and Chava were just created. They are naive and confused. They don't understand many of the important concepts in life, as seen when they try to "hide from G-d. But, this snake comes along, who also had just been created and is able to trick Chava into doing a sin. (Also, while we're on this lovely topic-how does the snake even know what Hashem told Adam and Chava not to do?) I don't understand what gave this snake the motivation to trick Chava, or why she even thought to listen to an animal, that she should be ruling over. The snake seems like its been around for a while, by the way it twists Hashem's words around and makes himself seem like he is right. As we can see, Chava who takes advice from a snake, and Adam who listens to her when she asks him to sin (without even questioning her) are clearly very naive and do not have the ability to do what the snake was able to. If the snake was "special"/sent from G-d, then why would G-d want to trick them? It would be like tricking a baby. They haven't fully learned yet how to distinguish right from wrong. Hashem knew they were vulnerable, so it doesn't make much sense to send them a sly snake who can make them think they can do something when they can't.
