OK, we really have you this time!
The crossover design of the human air and food tubes is obvious evidence for Design by a loving Creator!
I mean, who but a loving Creator could have thought that making the tube that we breathe through and the tube by that we ingest food CROSS, with a common opening that is only separated by a flap in the backs of our throats?! Sure, this flap gets into the wrong place fairly frequently, and sure, humans get food and water into our lungs pretty often, but the beauty and perfection of the Design resides in how often it DOESN'T happen!
Only a few thousand people each year end up choking to death, and that is also part of the Creator's divine plan.
Anybody who denies the obvious INTELLIGENT Design of this structure is just blind.
