“Calm down RF. Use your head.
If you were to travel to some distant planet and found a bolt, washer and nut miles from your ship, you could make a list of accurate conclusions.”
Those conclusions would be accurate in your case. To make it like the case at hand,
1. They didn’t find a bolt, washer, or nut
2. They found something that may look like a bolt washer & nut
So all your conclusions, while reasonable, are undermined for want of a bolt.
My goodness you’re closed minded. Peace
