You're reminding me of a miniminuteman video debunking this conspiracy theory, asking how it was that the aliens who built the pyramids were using the metric system.

I guess it's literally everyone in the galaxy except for Americans using the metric system.

So the reason the aliens always start their invasion or encounter with humans from America in Hollywood movies is because they are angry/curious to see the only people in the galaxy not using the metric system?
