Evidence of how our Moon formed... found?

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.

That is true, the Moon was formed from an Impact sustained by the Earth.
Our moon is very unique because it is large compared to the size of our planet.

the fact that the Moon was formed from an impact from an impacting event explains a few things.
1. the Earth's density, the Earth is denser than it should be. Has a larger metal core than is should have, this is because it is theorized that the Earth has a combined metal core from the object that impacted it.
2. the moon has almost no metals. Most of the metal was captured by the Earth. The moon is less dense than it should be for its place in the solar system.

Known as Catastrophic Theory: about 4 1/2 billion years ago an object the size of of Mars smashed into the Earth, as a glancing blow creating the Moon from the ejecting material.

Known as Catastrophic Theory: about 4 1/2 billion years ago an object the size of of Mars smashed into the Earth, as a glancing blow creating the Moon from the ejecting material.

Also referred to as the period of "The Great Bombardment". The Mars sized object was theorized to have been traveling at a speed of 250,000 mph when it smashed into the Earth. The debris from the impact formed into two smaller "moons" which circled the Earth at a very rapid rate. The two later collided to form our Moon. So a similar theory goes.
