There is no evidence of a multiverse. Ask anyone who promotes it ‘How many universes can you point to?” It is an unsupported hypothesis. But for argument’s sake let’s say there is a multiverse, it still does not answer the issue of the origin of the universe. All one has done is move the goal post back. The question now becomes ‘What is the origin of the multiverse?”
Since my opinion is considered bias, allow me to submit what Stephen Hawking has to say on the subject.
In this lecture, I would like to discuss whether time itself has a beginning, and whether it will have an end. All the evidence seems to indicate, that the universe has not existed forever, but that it had a beginning, about 15 billion years ago. This is probably the most remarkable discovery of modern cosmology. Yet it is now taken for granted… But if your theory disagrees with the Second Law of Thermodynamics, it is in bad trouble. In fact, the theory that the universe has existed forever is in serious difficulty with the Second Law of Thermodynamics. The Second Law, states that disorder always increases with time. Like the argument about human progress, it indicates that there must have been a beginning. Otherwise, the universe would be in a state of complete disorder by now, and everything would be at the same temperature… The conclusion of this lecture is that the universe has not existed forever. Rather, the universe, and time itself, had a beginning in the Big Bang, about 15 billion years ago. The beginning of real time, would have been a singularity, at which the laws of physics would have broken down.
