Feeling Nervous to Share, Am I Wrong for Considering Islam?

Assalamu alaikum, I hope you're all doing well. I apologize in advance if this gets a bit lengthy. So, I recently befriended a brother from Libya. We were chatting about Charlie Kirk and his newer interviews where he's against supporting Israel. My friend mentioned that Muslims actually honor Jesus more than Jewish people do, since Jews don't see Jesus as a prophet or messiah. I was honestly stunned-I had no clue. My heart softened instantly, and I started questioning what else I might have been misled about regarding Islam. I used to think Islam somehow hated Jesus and was all about extremist groups. After digging into the topic of Judaism and Jesus, I came across 'pre-millennial dispensationalism.' It's this idea from John Darby in the 1800s and the Scofield Bible that talks about supposed special plans for Israel. That's why a lot of Evangelicals in the US, and even many in Congress, back this way of thinking. My friend also shared some things that completely shook me. He said: (1) Every Prophet, from Adam onwards, came to guide people back to pure monotheism. (2) A Muslim is simply someone who submits to the One God. (3) Muslims pray exactly how Jesus prayed. (4) Muslims pray to the same God Jesus prayed to. These points really have my mind racing. I feel like I've been fed so many lies about Islam. I've been wondering why there's a long line of Prophets that Christianity largely ignores? Growing up, the only thing I learned about the Prophets was their 'examples of sin' in youth Sunday school. Beyond that, they never came up in daily life or services. Even as I explored Orthodox Christianity (I was Catholic before and studied Orthodoxy for about 8 years), I rarely heard about the Prophets, except maybe on a feast day I didn't know about. It feels like a big mistake that they don't play a central role in faith. Are they just overlooked? Then I discovered how the New Testament books don't all line up. Matthew, Mark, and Luke seem different from John. Scholars say John is one of the most Hellenized books in the Bible-it's not just that it was written later, but the language is so different from the other Gospels. The Greek philosophical style doesn't match the Semitic way Jesus would have seen the world. Plus, early 'Christianity' wasn't uniform. There were groups like the Ebionites, connected to the Jerusalem Church under James, who believed similarly to Muslims rather than in the Trinity. The same goes for the Galileans from where Jesus came-they likely upheld Tawhid. So, my mind and heart are spinning. Are Christians just following a Hellenized version of Jesus? I can't shake this thought. Paul and his letters (13 of them?) don't help, and I can't see him as a reliable source after all this. Also, my Orthodox Study Bible notes that many New Testament books are just 'attributed to' the apostles, not actually written by them. I'm upset-I always thought each apostle personally wrote those books. But in the end, I keep coming back to this: Jesus seems to have been Hellenized, and maybe that shouldn't be the case?
