How does this work?

Islam is built on the prophets of the Bible—yet to accept Islam, you must reject the longest-standing, most historically corroborated body of literature on the planet, with thousands of manuscripts, miracles, fulfilled prophecies, dozens of authors, and no errors or contradictions in 1,500 years—all in favor of one man’s word and nothing more.

I have questions:

Where was this teaching for the previous 2,000 years?

How does the “last prophet” contradict every previous prophet?

How is Jesus a prophet who says He is the Messiah, accepted as a prophet but rejected as the Messiah?

If all of this is explained away as “scripture was corrupted” then why didn’t Mohammad rewrite it correctly so they had one reference?
