in my opinion you're not correct here, you just think so, because you used language now for several years and didn't often use anything else. I believe that anyone can understand anotherone through telepathy without using language through telepathy, I mean sending words. There is the possibility of sending it in, what I like to call, Thought format(I'm a programmer so don't wonder). I think the deepest thoughts are in this "format" and anyone could understand them, because the mind would translate it that way since every mind understands that "format". You can become aware of that if you stop thinking on the surface and start thinking deeper. if you think there are a few possible wals to think:
- thinking loud, which would be with using voice, is not so really thinking
- thinking silent, which is when you think but others can hear, well most of the time hm, hm, hm,....
- thinking inside, which is when you think in language and you nearly can hear your thoughts although noone else will be able to hear them acoustical
- thinking deep, that is when you use no language to think, here you are not bound to any words, that is also for example when you thinking about a word and you know that you know it but you just can't find the word, here you know it in that "Thought format" but are currently not able to convert it into language. i have no idea what causes this inability, but let leave it at that.
One more thing:
If you know how to think deep, you are really not bound to language, that means you think faster than you would talk, a lot faster
A few words about pyramids: It is currently not known what they were good for and how they could have been constructed the way they are. Some archaeologists even think there was a fourth pyramid which was destroyed by its creators for reasons only speculated.
