You've completely misunderstood. I specifically said we don't have a time machine to see how the future plays out. All we can do is make our best guesses based on the past.
You've had to throw away basic reasoning tools that have been used for ages in order for your stance to remain "safe." I understand your fear, but honestly, you are better off embracing and understanding instead of putting your head in the sand and saying that we shouldn't use the past to make predictions of the future.
