In Kabbalah, Adam and Eve are two parts of the same Partzuf. When the Kabbalists want to emphasize the reception of this Partzuf they refer to it as Eve, and when they want to focus on its giving abilities, they call it Adam. And to understand the Thought of Creation, it was necessary to create a special Partzuf, which would exist in a special world, where this Partzuf could study the Thought of Creation of its own free choice. This is how the Partzuf of Adam ha Rishon was formed. Although Adam ha Rishon was not born in our physical world, it was quickly brought here and was given the name Adam, after its task, to be Domeh (similar) to the Upper One, the Creator.
