The universe is demonstrably finite and expanding, for about 13 - 14 billion years.

Although we are finding an abundance of extra-solar planets, many of which reside in the potentially "habitable" zone, we are also learning that there is an increasingly daunting number of factors that must coincide to form life as we have defined it, and exponentially more still for it to evolve even to our point. Even then, with intelligence and technology do they even want to reach out to anyone else?

Black holes don't do anything that breaks the speed of light.

Our universe may be an expanding bubble amongst other bubble universes but even if we could travel to them we'd likely die instantly if physics principles vary even slightly to those defined in the birth of our own.

Perhaps in lieu of traveling faster than the speed of light (even approaching it slows time and increases mass) these "aliens" could bend space-time to get around but good luck with that. Possible, perhaps. Likely, not a chance.

Now, consider the past say, 10 years pretty much everyone and their grandmother has a cellphone with a camera in it. Consider the past 40-50 years since the UFO first became popularized and made us want to be believers. No definitive photos or video. I can understand it being rare but not one video of a craft landing in a field with a big-eyed lanky grey alien stepping out to take a two-stream piss on their way to some Tatooine canteen.

Conclusion: unless you are religiously attracted to the alien phenomenon by faith and ignore logic and statistical data, one has to conclude that alien visitation to this planet is very unlikely.

To each their own but some people with little money and sense, and a faith in things like destiny and fate, love to spend money on lottery tickets as well.
