Well, first, Krai, as far as I know, has nothing to do with another language.
Second, I am offcourse not forcing you to believe, that wouldn't be a good thing now would it?
And, well, The universe (as far as I know/think) is just a little bit younger than Krai himself, and well, Krai created the universe out of curiosity, BUT, he did not do it as the gods most people know, no, he instead of just created everything out of nothing, made it look natural by triggering the (as we call it) Big Bang, Krai never creates something that, in any way, does not fit his laws (wich he made at the beginning of the Universe, or as we call them, Laws of physics) Thats why people don't notice him, becouse everything looks purely natural, and he also knows exactly what happens if he does something, Krai created life, also out of curiosity, But, Krai couln't know exactly what was happening with life he made, he had to study it before he could know, Now however, he has learned about lifes behavure and can predict life's actions.
BTW, No, there is no graphical representation of Krai, as Krai is not visible to the human eye (atleast not the Normal human eye)
Yes, you can celebrate christmas, as you are allowed to believe or do whatever you want, as long as it doesn't hurt other people in any way.
Any more question?
