Many a biblical scholar would argue that Sodom and Gamorah being burned was not due to homosexuality, but rape and such. But we can all speculate. Clearly prophets speculate all the time and it becomes the supposed word of god.<quoted text>
I don't know why it wasn't changed other than the answers I have provided. In God's time, 100 years is like 20 minutes? Maybe they were too tied up dealing with their own persecution at the time.
Again, I don't see how you think a prophet in the OT could be wrong about God's stance on homosexuality when entire cities were destroyed over the matter.
And what is science's explanation of different skin color?
The science I have read on the subject of skin color says when many generations of a people live in harsh, sunny environments, their absorption of sun changes. I can look up the exact chemical change if you wish,or maybe you can look it up in case you start to actually question the claimed words of god for a change.
Note, many generations is a long time depending upon the darkness. One estimate said a people may go from white to black in ten thousand years or maybe more. It is evolution.
