jews dont believe in Jesus either..

judaism (approx 300B.C.) was the original culture, which allowed (-10 B.C.- +10 B.C.) christianity, and then later the development of islam (around 750 A.D.).

it thus would have been impossible for moses to have stolen quotes from the qur'an.

The Tawrat and Injeel (it's funny how you didn't know the Islamic term for the torah yet make these insinuations, it shows how little you know about Islam) are both confirmed corrupted sources as per the Noble Quran, which did mention the Noble Quran and Prophet Muhammad (s) before their corruption, and there are traces of these mentions in those books. The dead sea scrolls as well has the Prophets (s) name written on it, the book of songs, etc.

Becauuse the Torah and Injil had been corrupted so those books could not confirm in the Quran

Really? Think about it.

Can older books reference newer ones? No. But newer ones, like the Koran, can reference older ones, like the Torah.
