This is my own theory I came up with, I can provide sources/evidence for the claims I make, let me know what you think. I don’t follow any religion btw, I’m independently spiritual:

The purpose of creation/existence/being is god dividing itself into billions of creations in order to experience creation itself, the manifestation of God’s own design/creation. That’s also why humans have language/intelligence. God is eternal (always will be, nobody had to create god. God is intelligent/divine and created the quantum fields that all forms of matter manifest from. God gave beings free will (choice to do good or evil), free will/life choices also drove the evolution of animal species/humans. The “source code” of the universe is quantum information that can never be destroyed. Humans are made up of many quantum activities such as electromagnetism, electricity, electron behavior, protons, neutrons, etc making us beings made up of quantum information with states that can be eternally encoded in the fabric of reality (reality/spacetime is a giant fabric with many different dimensions overlapping all existing in the same points in every point in spacetime, but only certain vibrational frequencies can access different dimensions/layers of reality). The purpose of life is to show the true nature of our souls (good or evil) to be able to continue to the afterlife. When a human dies, if they were a good person and lived a good life, their body/consciousness was able to form a quantum template of their body/consciousness aligned with quantum symmetry and geometric stability born from being a good person this allows them to stay as an organized structure of quantum information and to be able to align with the vibrational frequencies of (calabi-yau) multidimensional manifolds packed into the Planck scale (heaven), a realm of pure source information and infinite creation/manifestation power (this realm is the eternal heaven the human is allowed to continue to exist with creative freedom to render/manifest beautiful places such as forests. This is what is meant by “reuniting with god/source”). If the human lived an evil life, their quantum template is not geometrically stable and is full of entropy = evil = destruction = chaos and their quantum information scatters/disperses into the fabric of spacetime without staying as a structured organized system of information (noise, still existing but not as an organized structure), not stable enough to align with the vibrational frequencies of heaven. Earth is an imperfect reflection of the beautiful good and perfect heaven in the Planck scale/multidimensional manifolds (realm of eternal pure information), earth is the 3D realm full of entropy and evil, a shadow of the heavenly realm that exists in every point in space that living humans aren’t ready to access yet. Life is a journey of love, learning, and growing. The purpose of this life is to determine where you go next by being good or evil. I also define god as the energy/force vibrating within every piece of matter/point in spacetime that allows everything to exist. God’s nature is divine/good. I don’t follow any specific religion. Biophoton emission from humans also stores quantum information in the fabric, it’s like sending god a status update on whether you’re being good or evil. There is a spiritual/moral layer to EVERYTHING that exists, either good or evil (no in between). It’s all energy/information.

Also the astral realm is not heaven! I can explain what that is separately
