I've held off on answering primarily because I didn't understand the question--or more accurately, where it came from. Frankly, despite the re-asking, I still don't.
The Hebrew Old Testament scriptures have come down from well before the time of Christ. Ray pointed out that the "script" used in some of the scripture was changed from one type of "writing" to another type (block lettering) and why that occurred...and that it occurred well before "modern times" or even before the Septuagint and the time of Christ. Those were the scriptures in the Temple and in all the synagogues, and as far as I know, those are the scriptures still in use...both in the synagogues and in translating modern bibles.
I don't know about "aramaic", but I am positive that "Yiddish" is a much more recent language (based on Hebrew) that developed during the "diaspora". Hebrew as a widely-used spoken language died during those centuries, and remained dead until quite recently. The OT scriptures, however, did NOT die and have come down to us intact from well before the time of Christ. In Hebrew.
It would surprise me if modern colloquial Hebrew wasn't influenced by the languages of the places Jews settled during the diaspora (Russian, Polish, German, English, etc). It would surprise me further if modern formal Hebrew wasn't based on the vocabulary, "alphabet", syntax, and pronunciation of Old Testament Hebrew. How "identical" they may be, I can't say.
Spoken language affects written language, and written language affects spoken language.
It's worth remembering that, just as the bible was not written in English, neither was it written in "modern" Hebrew. "Modern" Hebrew is based on ancient Hebrew...not the other way around. Our "modern bibles" are translations of either ancient Hebrew texts (not scraps, but entire scrolls) or of translations of other languages translated from the ancient Hebrew.
So...you asked "...is it true that the Hebrew in modern Bibles is not the original Hebrew Language - and that there are no modern day Bibles with the original Hebrew Language?" The answer is NO to the first part, and Almost Certainly Not to the second part (I don't know ALL modern day Bibles), with the understanding that NO MODERN DAY BIBLE is in the original Hebrew Language EXCEPT FOR THE HEBREW SCRIPTURES, which are.
Most all my print and 'virtual bibles' are in English from cover to cover save a few words here and there, though I have a Hebrew OT and a Greek NT, only one of which I can 'read' at a second-grade level.
