comments? sure!

The Mt. Rushmore example doesn't doesn't cut it. Rocks don't "evolve".
If I found a complex carving, or modern machine in 1,000,000 year old strata, then this WOULD cause me to wonder, but humans are complex because they are entities built of 'stuff' that is inherently able to evolve.

The error in the example involves 'equivocation', which means that different types of 'complexity' are being compared under rules which don't apply to both.
