A question is begged from this giant impact hypothesis.
Is a collision between two astronomical bodies essential for life?
We know our planet has a global 'ocean' of magma and strong magnetic core. Volcanoes though destructive, are essential for plant life upon which animal life and food chains are ultimately dependent, regenerating the planet's surface and spewing out much-needed minerals.
Considering our world is in the Goldilocks zone, the habitable region from the parent star.
And an outer gas giant, such as Jupiter is also fundamental in its role as a "cosmic vacuum" catching the majority of stray asteroids and comets that might otherwise obliterate life in its early evolutionary stages on this developing world.
It seems the criteria for life, is getting more and more and more strict and unrelenting, the more we learn about our hostile cosmos.
