You must be super fucking dense.

Judaism, Christianity, and Islam all believe in the exact same god.

They have different names for Him, such as Yahweh (Jews), God (Christians), and Allah (Muslims).

They all believe Jesus was real.  Jews think he was prophet, Muslims think was a prophet and the messiah, Christians think he was prophet messiah and son of god.

Jew are still waiting on the messiah, Christians and Muslims are waiting on his return.

These are core tenants of believe for all of “the people of the book.”  They can’t be argued away because they are simply fact. If you think otherwise you are extremely delusional.
