Evolution's time-line is much longer than 10 million years.
The moon impact is put at 4.5 billion years ago, and that Late Heavy Bombardment (LHB) is said to last from 4.1 to 3.8 billion years ago (bya) -- coinciding with the first possibly biotic material found in Western Australia from 4.1 bya.
The first certain evidence of life dates from 3.8 bya in Greenland, and the first microbial mat fossils date from 3.5 billion years ago in Western Australia.
Therefore, these new finds in South Africa are among the oldest, and correspond to times set for the last common ancestor of bacteria and archaea, circa 3.5 bya.
So, it appears to me that God wasted no time creating life on Earth, as soon as He was satisfied conditions here were suited for it.

Scientists just discovered life began 300 million years earlier than anyone knew

Researchers have found evidence of ancient microorganisms that lived in what is now Western Australia at least 4.1 billion years ago. If confirmed, the discovery suggests that life originated on Earth 300 million years earlier than previously thought.
This would mean that life originated not that long after the formation of our planet - just over 4 million years to be precise - which might sound like a really long time, but it’s a proverbial blink of an eye in the history of Earth. It would also change our understanding of what it takes for life to form here, and, excitingly, elsewhere in the Universe.
“Life on Earth may have started almost instantaneously,†said one of the lead researchers, Mark Harrison, a geochemist from the University of California, Los Angeles. “With the right ingredients, life seems to form very quickly.”
The new research also suggests that life existed on Earth prior to the massive bombardment of the inner Solar System - a period of intense asteroid activity which formed the Moon’s large craters around 3.9 billion years ago.

An extraterrestrial origin for the fundamental organic precursors and/or preexisting Life cannot be excluded as the source or sources of Life on the Earth.
