There has not been enough time.
Shuffle a deck of cards. Deal five cards face up. If you do not deal a royal flush then re-shuffle and try again.
After you’ve dealt a royal flush buy a lottery ticket. If the lottery ticket doesn’t win the top prize then start over shuffling cards. If the lottery ticket wins the top prize then take a teaspoon of water from the world’s oceans, lakes and rivers and put aside.
Now, start from the beginning and repeat until the oceans, lakes and rivers are dry.
When the oceans, lakes, and rivers are dry place a sheet of paper on the ground.
Repeat all of the above steps placing the second sheet of paper atop the first and so on.
When you have a stack of papers that reaches to the moon then enough time will have passed to allow for life to arise spontaneously.
That’s great!
