No offense, but I don't think you're thinking it through clearly here.

If they think you're crazy and into conspiracy theories, that means they've probably already heard enough propaganda about it to be a denier. There won't be any meaningful discussion. It won't matter what proof you provide or how you lay out your case, it will only fees the denial.

But.

You have to remember, it's a lot. You didn't come to it in 20 or 30 minutes either. It took a while. If theyre not saying anything, that means they don't already know, vut they're not dismissing you out of hand either. You need to give them a while to sit with it. It's a lot. Remember? They're gonna look for ways for it to not be true, just like you did. It's going to take a decent amount of time and reflection and education to get to the point of resolve.
