But How Did it All Begin?

A simple enough question, but that is rarely indicative of the answer's simplicity. The problem lies entirely on the silly little word "all". What is all? It's beyond our scope as humans for sure and it makes answering the question impossible. How can we answer for everything when we are not even aware of what everything is?

In the story of Zeus and Europa it's made clear that their story doesn't begin with the event currently being presented. It goes back to Zeus and Io who started the circle of abductions in the family line, but it goes further back than that. Without the coupling of Zeus and Hera, there would have been no abduction. Without the coupling of Kronos and Rhea, there would be no Zeus and Hera. Without the coupling of Ouranos and Gaia, there would be no Kronos and Rhea. It's at this point where the classical mythology runs into the same problem that all mythologies present. Where did Ouranos and Gaia come from?

Like a parent trying to answer their child's barrage of "why"s, there is a point where our knowledge and understanding fail. What was the universe like before the Big Bang? Where did Ouranos, Gaia, Apsu, Tiamat, Rangi, Papa, Vishnu, or Yahweh come from? Fortunately, a good story doesn't have to account for everything. A good story starts where the intrigue does. If myth is the precedent behind every action, then it only needs to encompass the actions that effect our lives. For Europa, the story begins with Io because that is where the abductions begin and that is the defining event of Europa's life.
