Appending thread title for accuracy:
"Mathematical reasoning why aliens will never visit."
"Mathematical reasoning, created by an individual who is part of a less than 1 Kardashev civilization, why intelligent life, as they know it, will never make an interstellar voyage to the planet of said less than 1 Kardashev civilization. This reasoning utilizes knowledge and engineering that they have developed and explores those options as if no others exist."
-=-= "There are other continents on this planet, but those people will probably never come here. Why not? Your arms would get tired after swimming a few miles. There are thousands of miles between them." =-=-
I appreciate your methematical reasoning. You sure do know a lot about interstellar travel options.

There are counter claims and thus different ideas to every claim made on this subject, for example and if my understanding is correct, the estimation of stars in the observable universe is something like 1000,000,000,000,000,000,000,000 stars, and even then some people say that's an under calculation.
With numbers like that and our limited knowledge, you could say that it's practically impossible for their not to be other life out there.
However, until more is known, it's a case of pick whichever theory you like best

Or any other civilizations that do emerge/have emerged may simply come to understand the limitations of using radio waves as a communication medium on the cosmic scale and have now graduated to other means of communication that is above our technological prowess to detect.

Let’s take a look at probability. Given our own Sun is 4.6 billion years old out of a 13.8 billion year old universe, that’s only 33.33 %, or about one third. We already missed two thirds of the time during which things existed in the Universe, before our sun was even created. That’s 9.2 billion years, it’s also a really, really long time during which many things could have happened.
Out of the millions of species on Earth, only a handful have evolved to the point where they can use tools, and only ONE has above average intelligence useful for learning science and math. Out of the 7 billion people on the planet with this ability, only a few thousand of those people have the advanced knowledge to be able to send communications into space, or for that matter, spacecraft.
The universe is largely thought the be about 93 billion light years across. So for 0.000000002 % of the time that Earth has been around, civilization has been sending out a random signal to 0.0000000025% of the Universe, hoping someone will hear it at the particular time in their own development that we assume is similar to the 0.000000002% of the time that we’ve had communication ability.
And wondering why no one called back, or came to visit.

Whilst the speed of light in a vacuum, is a fundamental constant central to much of physics, particularly Einsteins theory of relativity, which is the problem really, something like the Albercurrie drive concept may then allow us to circumvent the speed of light in rather a more interesting fashion.
