The problem is, isn't it, that at one level you have things that appear fine-tuned, and at the other end, stuff that is clearly a complete dogs' breakfast!

The First Cause, if we assume for the moment that it is intelligent, seems to have had all its quarks, quanta, mesons, bosons and tachyons in apple-pie order, but then got all ham-fisted with its' living beings!

To take the obvious example, mammals and reptiles all seem to have one of their most vital organs -the brain -stuck out at one end of the body on a fragile stalk, rather than safely tucked away in the thoracic cavity with the heart and lungs. Not smart. Also, the extremely useful ability to regrow severed limbs seems to have been left behind in amphibians and reptiles. Again, not the mark of a particularly bright, never mind intelligent, First Cause.

This brings me to several thoughts.

Is the FC that did the physics the same being who created Life, or are we talking collaborative project and/or unlicensed interference here?

Was the creation of life actually part of the intention, or is it an error or side-effect?

Is the FC even aware of much of the Universe? Or are they concentrating on specific mechanics and reactions.

Or, once the FC had satisfied themselves about the physics, did they simply put the project to one side in order to start something new, and are we the dust gathering on it or a result of its' decay?

Because if any or all of the above are even partly true, then the eventual proof -should any be found -of the existence of an intelligent First Cause will solve nothing. It will simply be another naturalist fact, and life will remain without meaning or purpose, unless we choose to give it one ourselves.

Devils' Advocate, it's what I do 😊😈
