My impression of this quote is that only young children know everything. When they get older and slower in the mind, they are less likely to believe and therefore to less likely to know the most about unusual but interesting things.
Children believe in fairy tales or some forms of magical happenings, and they also believe in scientifically-incorrect theories such as aliens and Area 54. They believe in certain legends, myths, and fables, and all kinds of other stories.
Oscar Wilde was sometimes called the Man of Barbed Wit, because he could think of many insults to spout at one time that made many people laugh, and many people scowl. He was extremely smart until the day he died; never letting anyone place him as the butt of a joke.
He is saying in this quote that you only believe all those amazing things once, when you are a child. After you age, you begin to think of all those amazing things as foolishness, infantine. This is why it is good to enjoy being young while you are.
