The "Multiverse" concept doesn't lead to the conclusion you propose for it. In fact, with the "Multiverse" all things are possible, one of which is a Creator God ~ even a pantheon of gods somewhere ~ for an instant.
Once you get a Creator God, that's the end of the discussion.
You will find that the anti-God crowd really doesn't want to pursue further examination of the "Multiverse".
Which raises a question ~ why are you now aligned with the Atheists?
No, a 'multiverse' (which is most assuredly not a scientific hypothesis in the Popperian understanding of science) does not imply the non-existence of God, no more than the neo-Darwinian synthesis as an explanation of biological diversity does. What it does do is allow the atheist to explain away the obvious evidence of design in cosmology.
If you think I am "aligned with the Atheists" because I point to the undoubted fact that the Darwinian mechanism can be harnessed to create novel complex algorithms, you are mistaken. I suggest you read Alexander Kalomiros's The Six Dawns to disabuse yourself of such notions.
