" it's the best explanation for why we find ourselves alive and in a universe that allows our existence.".
That's the wrong way round. If the universe wasn't fit for life, life wouldn't exist. Indeed there may be many other universes where life can't exist.
The multiple universe hypothesis is on the same level as the god hypothesis as no-one can see "before" the singularity, if that word even makes sense in that context.
The multiple universe hypothesis however, does have maths to show it's possible.
