ALTER2EGO -to- DEFIANT:
You are referring to human imperfection due to sin. The first two humans (Adam and Eve) were created with perfect physical bodies and had the opportunity for immortality. But, they chose to reject Jehovah's instructions. So he withdrew from them the opportunity for everlasting life and they immediately began to die. They then passed death on to their offspring: the rest of the human race.
"That is why, just as THROUGH ONE MAN [Adam] SIN ENTERED INTO THE WORLD and death through sin, and thus death spread to all men because they had all sinned." (Romans 5:12)
Clearly, what is happening to humans in no way affects precision elsewhere (the millions of planets in the heavens and their relationship to each other, the example in my OP of the elements on the Periodic Table, our fine-tuned universe, etc.)
