Considering how vast the universe is in terms of space and time, there have been/are/will be billions of life-supporting planets, so your glib derision is simply glib.
To the contrary: the universe ain't nearly as vast as the problem. You'd know that if your understanding were anything but second hand.
Try quanifying the problem before making "glib" assertions with only tenuous connections to reality.
Got proof? Thought not.
How does something that is dead magically come to life, with the ability to collect energy from the environment to sustain its metabolism, and then some time later, even more magically reproduce a copy of itself that also has all those abilities?
Absent God, it ain’t gonna happen, no matter how many billions of years and billions of galaxies and billions of stars you want to count.
