Abiogensis[1] is your key word for today. Study of how life was created from non-living materials.

That scenario is not the most likely. Doesn't require a supermassive collision.

We don't know the origin of life, but we do the know the building blocks. We can find all the building blocks on many comets and in the interstellar space. As in, you could fly out into space and collect enough stuff to make a cell.

The two main candidates for that initial spark are underwater volcanoes and surface bodies of water that dry out / re-fill.

And bringing it full circle, one reason that there are so many surface bodies of water that dry out and refill is none other than the moon! Many credible theories rely on the presence of the moon-driven tides to stir up matter between land and ocean.
