### The statistical odds (and common sense) against UFO/ET visits

Universe Today:

[There are] 200 to 400 billion stars in the Milky Way [alone]

{There are] 100 to 200 Billions galaxies in the visible or known universe with hundreds of billions of stars

An average galaxy contains between 1011 and 1012 stars. In other words, galaxies, on average have between 100 billion and 1 trillion numbers of stars

[Galaxies can be] small dwarf galaxies, with just 10 million or so stars, or they can be monstrous irregular galaxies with 10 trillion stars or more.
------------------------
NASA:

In 1999 the Hubble Space Telescope estimated that there were 125 billion galaxies in the universe, and recently with the new camera HST has observed 3,000 visible galaxies, which is twice as much as they observed before with the old camera. We're emphasizing "visible" because observations with radio telescopes, infrared cameras, x-ray cameras, etc. would detect other galaxies that are not detected by Hubble
--------------------------

Based on current estimates, there are between 200 - 400 billion stars in our galaxy (The Milky Way).

There are possibly 100 billion galaxies in the Universe. So taking the average of our galaxy, gives approximately 3 x 1024 stars. So about 3 septillion. This has been equated to the same number of grains of sand that are on Earth.

One source (BBC) stated that there are about 1,000 stars to every grain of sand on Earth!! There are an estimated 100 to 200 billion galaxies.

So taking a conservative number of 100 billion stars per galaxy gives an approximate total of 10,000,000,000,000,000,000,000 stars. (Which is 10 sextillion)

Wikipedia:

Alpha Centauri is the closest star system to our Solar System. It lies about 4.37 light-years in distance, or about 41.5 trillion kilometres, 25.8 trillion miles or 277,600 AU.
------------------------------
With the information above, how can anyone, with an ounce of rationality, think that UFOs represent visitors from galaxies, far, far away, or even from the nearest star system to Earth?

The Universe, with its vast diversity and intriguing panoply of astronomical or cosmological entities (by which we mean stars, planet, moons et al., not living beings), offers any curious alien intelligence much better sources for exploration than Earth which, in the great scheme of things, is a backwater and insignificant cosmological element, no matter how hard humans try to think otherwise.

Even if an alien exploratory team stumbled upon Earth millennia ago, what would stir them to keep visiting for centuries or eons afterward?

Of course, some ET believers say Earth was seeded by alien visitors and they keep coming back to see how their humanoid garden is doing.

Or Earth is a penal colony or some sort or a zoo, and extraterrestrial aliens keep checking in or visiting as if this lonely, remote planet is an integral part of a special alien agenda.

The idea that UFOs, with their abundant sightings, represent extraterrestrial visitations in light of the statistical probabilities above which open the whole Universe to such visitations, is ludicrous on the face of it.

No wonder that UFO devotees are seen as cranks and weirdos. Their thought processes invite the opprobrium.
