Dear my respeted senior, @valued-customer !
Thank you for kind answer!
By the way, I felt like you were overpraising the awkward English sentences of American elementary school students!

Steve always advised me to be careful with my English words and sentences! He said my awkward English could offend, misunderstand, and even anger some people!

East Asian historians, including myself, believe that the civilizations of the Indian subcontinent had a great influence on the birth of East Asian civilization!
So, I believe in the Indo-Aryan theory created by European scholars!

But, I remember that in Islamic civilization they do not believe in the Aryan theory created by Europeans!

Because of the Aryan theory, scholars in East Asia believe that European civilization is superior to Islamic and Indian civilizations!

I'd like to talk to you about that area later!

I hope your health and long life!
