Some recent theories suggest that huge numbers of big bangs of different

different matter/antimatter ratios and other factors. The vast majority
of these universes are unsuitable for life, but there are so many of
them that a few end up with just the right conditions for life to be
possible.

M-Theory suggests that a big bang occurs whenever two Branes collide. It
may well be possible to test M-Theory when we develop the technology to
detect gravity waves, because gravity travels between Branes, and big
bangs occurring in nearby branes should be powerful sources of gravity
waves.

But is there any evidence that such universes exist? And if this was
happening, would not they collide, interfere with our universe?
The odds of even our universe existing are so remote, that its a
miracle we are here! Which leaves the question, why are we here, why
not no universe at all?

No hard evidence at the moment. It's generally considered that it may take up to a century to convincingly test M-Theory. You could attempt to falsify it if you had a good gravity wave detector or a collider a few orders of magnitude more powerful than the LHC. That's why it's just a theory, on the same sort of level as String Theory, Supergravity, Heim Theory or Loop Quantum Gravity, just considerably more elegant than some of those and with more practical applications than others.
