How do you know its the Sahara?
This is getting ridiculous.
First Mysteryman, I have been to the Sinai peninsula. The Sinai and the Sahara are very different geologically. The Sinai doesn't look anything like that. You are of course correct there might be one place in the Sinai that happens to look like that if you hold the camera just right in the exact right spot. Then again it could be in Minnesota for all you know.
This was just a suspicion. But of course when things don't look right, there are ways to confirm your suspicions that the image or story you are being presented with is bogus. In the original discussion these methods include genetic tests, reading records from the time period or looking for the obvious signs that would be left behind by a mass migration of tens of thousands of people.
In this case the evidence this image is not the Sinai is easy to get. I did it and you can even do it yourself. Simply Right click on the image and then open the image in a new tab/window. Then look at the filename which reads (in plain English) "lonepalmsaharadesert". Then again, you could have taken a few minutes to google and read about the Sinai peninsula. Just look at the pictures of the Sinai and tell me the difference isn't clear to you in two seconds.
Of course, Mysteryman, you don't have to accept this evidence. If you want to believe this picture of the Sahara desert is actually the Sinai where tens of thousands of Jewish migrants allegedly walked across to their promised land, there isn't much I can do to change your mind.
But to any rational person looking objectively, the facts are pretty obvious.
