OP, hypothetically if there was an Extinction level event, what happens to all the trapped souls in the earth matrix? Would they be liberated? Reincarnated onto another planet? Stuck in the astral forever? What are your thoughts on this scenario?

Much of the creation in our simulation is actually programmed from the level above just like a programmer would create a video game. In mere days entire galaxies can be created. Solar systems are not made by random chance. They all follow certain rules during creation. Some planets actually span many time dimensions and actually have a purpose we cannot see or hear. Once the system has been created it is prone to random chance as is everything within the matrix. When the powerful programs fell into this level permanently they lost the ability to create quickly. This then lead to the powerful programs trying to reach the next level below us and by doing so much of the construct could be manipulated further.

In the immediate vicinity I can tell you Our previous prison home for some programs was called Malduk. This planet was destroyed and blown up by war and is now the asteroid belt. It was originally thought the trap mainframe existed in the planet Malduk and by destroying it we could be free. This however is untrue as this entire sector of the simulation has a part to play and the traps systems are widely hidden and dispersed in multiple dimensions. Ceres was a moon satellite orbiting Malduk. Many programs incarnating here lived lives on Malduk millions of years ago. The floating asteroids that are now locked into orbit around our Sun are chunks of Malduk that are still in orbit. One such chunk hit earth millions of years ago resulting in the extinction of the dinosaurs.
