The thing that makes something ‘scientific’, rather than ‘faith-based’ is that it can be proven wrong. Think of it as our best guess so far, rather than some incontrovertible truth.

I am sure a basic search will return plenty of well researched and evidenced books on evolution.

As an aside I will say that I heard an interview with a data scientist whose recent work had found that genetic mutations weren’t random (in some way). Which could potentially throw an interesting wrinkle in there, lol. The bloke I heard interviewed stressed his paper had not yet been peer reviewed, and, iIrc, really just pointed towards the need for more research. I am just mentioning this as a bit of an aside.
