In a nutshell, the argument posits existence depends upon the conscious perception. The argument is a bit pedantic, given the existence of God, His omniscience and He is the Creator.
The universe is a virtual reality, and our bodies are avatars controlled by our minds in our unconcious celestial bodies, interfaced via the brain.
When we die, we awake in Heaven back in our real bodies, to face God, who will judge us as to whether we chose to follow Him; or chose to reject Him, and work for The Adversary, Satan.
That is why it is written in Ecclesiastes, that when we die our soul returns instantly to He who made it.
He set the whole thing up as a test, after a third of us followed Satan in his original rebellion.
Those who ‘pass’ the test, recieve eternal life, but the others....
Other explanations’ milage will vary.
