The more simple answer, to me at least, is that there's an infinite Omniverse there, and you're an integral part of it. It has the inherent capability to do everything that ever happened and ever will happen, and the scope of what can happen is infinite. Some of the inherent qualities are self-reflexive consciousness and the ability to evolve. It is vast, complex and mysterious, but ultimately completely logical and coherent. You can learn about it and understand it as deeply as you want, and it will readily divulge its secrets, but everything in it is connected with everything else, and all of it is continously evolving, so you'll probably never be done. And that's what makes it an infinitely continuing and expanding game.
