Yesterday, I found a VERY complex assembly of organic molecules in my yard.
It weighed a few pounds, I suppose, and looked VERY similar to living organisms that scamper from tree to tree; performing inhuman feats of aerobatic gymnastics.
I couldn't tell how many minutes (hours?) had passed since this assembly actually was a LIVING complex assembly of organic molecules; but it sure wasn't when I lifted it by it's bushy tail.
It appeared to be missing nothing that would have caused it to be NON-living: no holes, no leakage - just no LIFE!!
In all of human experience; we've NEVER detected LIFE coming from NON-life.
It ALWAYS takes something LIVING to propagate itself.
