Maybe Adam spoke Lashon Hakodesh? Definitely seems like that. “
Hebrew was the language of Creation, and that is what Odom spoke. it was not until Migdal Bavel that language split into 70 different ones. There is a very interesting book, the name of which escapes me, that was brought to my attention by my Rov. Its thesis is that EVERY language spoken today can be traced back to Hebrew. Certainly, I have seen such evidence in many cognate words that clearly have Hebrew roots in them, and I do not mean English language words that have been Hebraicized when put into a modern Hebrew sentence.
Look in our davening at the language of the ingredients of the Ketores, for example. I don’t know if it is the same item, but Tziporen sounds very much like “saffron.” That is not an accident. How about Milchemes Gog U’Magog – Armaggedon? There are many such examples.
