I have watched it a lot in most Marvels movies like The Flash, Avengers, Infinity War, End Game, and Doctor Strange in the MultiVerse of Madness. I have come to accept that there’s a possibility of the multiverse being real. We shall find out one day soon enough.
What I’m very sure about is that we have possibilities of aliens living amongst us. Even our government is covering up their existence among us. But as for multiverse, I’m not sure about it.
