I truly believe we are only here because our universe is infinite, and all permeations are possible. We are that permeation against all the odds. But since we are possible then exact copies or so close it to exact copies to make no difference must exist as patterns repeat in an infinite system. Now, can you imagine all the permeations possible if multiverse theory is correct? No, you cannot because no one can. Writing out the number of possible universes on a sheet of paper at the microscopic level, just the ink alone would collapse into a black hole. All those spidermen getting sucked into one universe at once would have probably been enough mass (energy,  E+MC2) to force our universe out of the current false vacuum and turn everything, I mean everything into goo
