yea i recon probably English (i already know it too), then Japanese or Chinese or something like that that uses an entirely different character set that the European languages .
sanskrit.. its the most difficult language in the world... every language survey proves that...it was one of the first languages... started in old old india..
Sanskrit is the oldest language in the world and it's created by Aryan people who invaded India between 300-500B.C or like that. It's difficult like Latin.
