Fine.....Use this logic to prove the Revolutionary war took place.
Can't see it (camera wasn't invented)
Can't taste it, hear it, feel it or smell it.
You can say "We don't belong to Britain anymore," which we know is true, but you can't prove it using the five senses.
I can't see, taste, hear, feel, or smell it because I wasn't there.
But there's existing evidence. There are still items that are being found on battlefields (muskets balls, bits of cloth and paper, coins with the date legible, etc).
And it's easy to prove this land doesn't belong to Britain anymore.... I can see the flag of the USA flying in various locations. I can see the Declaration of Independence. Now, associating those couple of things with a bit of logic and common sense would lead someone, even with slightly below average intelligence, to the conclusion that the USA is an independent nation.
