Question or Comment: This is a question about fine-tuning. Considering how sensitive the physical world is to even minor changes in all the constants in our physical laws, it would seem that no matter what values these constants took, you would end up with a universe that had unique features. It’s hard to imagine what those features might be, but it raises a question. Why single out life as the thing toward which the universe was fine-tuned? Granted, life is unique to a universe that is tuned the way our universe is tuned, but something else might be unique to a universe that was tuned differently. So why does the life-permitting nature of our universe give us a reason to suppose there must’ve been a designer when any other universe wouldn’t give us reason to suppose the same thing?

My response is below:
Imagine if you were an explorer and you encountered an island that you supposed had been uninhabited. Upon exploring the island you find a letter with English lettering spelling out the phrase, “I have lived on this island for 10 years.”
Should you disregard the conclusion that an English speaking person had visited the island because, had the letters been shaped differently, the letter would have been in a different language?
For the same reason, we are reasonable for concluding in our universe that it is finely tuned for life no matter what may have been the case in a different universe. Perhaps in a different universe we would have a different sort of fine tuning argument, but such a hypothetical scenario would not have any impact on the fine tuning argument in our universe.
