I’m sure some will say? The assassination of JFK! Of course! What about the assassination Abe Lincoln? MLK?
The making of the H-bomb? The starting of wars? Conflicts?
The point I’m trying to make is? With what we know today. Would we be able to prevent it?
All the things that went on in the past. Were made by what was known in those life & times.
What if? /We could go back? And save the human race?
What point in time would you want to save? And why?
