You will be very surprised now.

Doubt it. I expect you to start moving the goalposts and completely ignore the test criteria you gave yourself and you do not disappoint.

For the record - the test you laid out was that any word from any language phonetically or structurally similar to "karan" would have - as a part of its etymology or semantic core - one of the following - angle, horn, beam, cow, fish, god, horn or boat.

Given the failure of this prediction, your hypothesis would as well.

Crane – look at it’s shape. As a bird it is crescent like shape. And as a mechanism it forms angle which was appearing several times during my explanations:

Sorry, not a crescent.
Even if it was, the shape is unimportant - the etymological root of the word has nothing to do with the moon.
And the name of the mechanism is the consequence - not the cause of the name of the bird. Therefore, even if "angle" was part of the mechanism, it still isn't a part of the word's etymology.

And also some cranes have a crown on his head

Also irrelevant. The "crowns" have nothing to do with naming the bird.

This bird is a divine bird in preislamic religions. There were three goddess Al-Manat, Al-Uzza and Al-Lat which were called “three honorable cranes”. One of this goddess was portrayed with two fishes on its head.

If you remember I told that fish is one of the ancient moon symbol. Jesus symbol is fish.

So? None of it is relevant to the word's etymology. Cranes being associated with fish is, in itself, quite trivial and meaningless.

Green – etymologically goes to

Old English grene "green, young, immature, raw," earlier groeni, from West Germanic *gronja- (cf. Old Saxon grani, Old Frisian grene, Old Norse grænn, Danish grøn, Dutch groen, Old High German gruoni, German grün), from PIE root *ghre- "grow"

Growing moon is the epithet of crescent. Crescent is usually called “young moon”.
Root “grow” was already mentioned with connection to the moon in "crescent" etymology which comes from PIE root *ker- "to grow".
In our country for somebody young we say “he is green”.

And what this shows us is that the semantic core of both is the PIE root *ghre- "grow" - which wasn't in your list.

Its quite simple - the crescent moon grows - which is why the word is derived from that root.

Similarly, grass grows which is why its the name of its color is derived from that root. They're connected by a common root - but "crescent" itself is not the root for green.

Neither in meaning nor in etymology, any of the words of your list are present. Thus, once again, it fails.

Crone – the etymology of this word comes to PIE root *(s)ker- (1) "to cut"

Look at the instruments used by ancient people to cut something and will understand what connection it has to the crescent shape.
Egyptian stone knives:

Knife of Eskimo of Siberia

Slavic tribes were having a wearable mascot of the cutting tool. This mascot is moon symbol in their tradition.

Pay attention how english word "mascot" is similar to Moses, Messiah, Mesyac etc.

Why the word “crone” is used to describe an old woman? Because of its shape!

The humped corn is the famous magic character of Russian folklore – Baba Yaga. It is the night witch. With witch celebration in full moon day.

Giving pictures of a few kinds of knives that vaguely resemble a crescent is not sufficient to establish a connection between the PIE root *ker and the shape itself. Especially since the root of the shape has already been established as independent from it. Once again, nice try, but no cigar.

Through the etymology of the word crone we see the root *ker meaning "to cut", which gives us carnage which goes to carrion and then onto crone. Neither "crescent", nor its root nor its shape is significant here and showing the pictures of a few knives doesn't change that.

Karn (sanskrit) –
I have found Karna (करेणु), which means “ear, bore, pierce, handle of a vessel, helm of a ship.”
Ear was already mentioned in Rig-Veda example it has crescent like shape and the ancient earrings mostly had special form which symbolizes god people respect. In India this type of earrings is still wildly used. For example in national Karnataka costume.

Sanskrit "kareNu" is atranslated as elephant – the animal famous for its ears and tusks (white crescent).
And there is the predicted god appears. Ganesha is the god represented as elephant. It has only one tusk according to the tradition.

And here's why it fails your test - the root meaning of the word "Karna" is "ear". That's its semantic core. All derivative meanings are based on it meaning "ear". And despite your claim, the Rigveda does not use "ear" to symbolize a crescent or moon. Whenever and wherever something can be seen as an ear - as in "being led by the ear" the word karna can function as the root meaning. Thus its use as handle of a vessel or rudder of ship.

On other note - the shape of earrings are circular - not crescent. And they do not have a special form symbolizing respect - they are an accessory.

Further, the word "ear" is used in one of the words for elephant because of its big flapping ears - nothing to do with tusks. Also, you'd find quite a lot of animal gods in Hindu mythology. Elephant was bound to come up.

Karin (花梨) – if you talk about this kind of fruit known as “Karin” in Japan you can see that inside it has two moon like shapes.

It means "Summer Forest" - probably the reason for the name of the fruit based on its season. Once again, your moon analogy fails.

So as you can see with all wildest range of meanings existing in our mind the set of possible semantic variations is very limited.

Actually, what I see is that while there is no etymological or semantic relation between phonetically similar words from different languages, anyone can find some arbitrary, miniscule detail of similarity between the objects those words represent and regard it as significant.
