Fine-tuning cannot be proven, of course, but there are plenty of ‘cosmic coincidences’ that enable our being here with high tech and heavy metals – even our particular location in our particular kind of galaxy.
In 2017, near the time of the total eclipse of the sun I read where one secular astronomer called it “magic”, the fact that the disc of the moon in the sky ‘coincidentally’ so closely matches the disc of the sun.
It is cool that it sure appears that the universe was designed to be discovered – from here, with our special moon. Huge amounts of knowledge about how stars work has been discovered – and more is still being discovered – during total solar eclipses. And that is not to mention all of the other details about why so much of the cosmos is visible, unobstructed, from here.
