Mt. Sinai's True Location

I came across this video some time ago. I found it to be very entriguing. The Bible states that this mountain was in Arabia (Saudi Arabia today), and yet in the back of every Bible in the maps section, it is in Egypt.They don't even cross the Red Sea in most maps found in Bibles. If modern day scholars couldn't get this right, what else did they get wrong? I do not own this video and in no way promote the belief system of it's owner. Here's the video, which proves the real location of Mt. Sinai.

The apostle Paul knew where Mt. Sinai was. And it's still there.

Galatians 4:25

"For this Agar is mount Sinai in Arabia, and answereth to Jerusalem which now is, and is in bondage with her children"
