I used this presentation in a Bible study for youth, and they asked great questions. It's not the "scientific" timeline at all, so, it's not what we are usually taught. On the other hand, it's what God inspired, and there was probably a reason since they could do math back then too. Anyway, it's a 15 minute video, so make sure you have the time to watch, or plan to watch in segments. I suspect you will be surprised. I was blown away.
I hope you are blessed by it.
