Life is a mystery. We don't know what life is other than arrives in a spark and ends sometime later in a flash. We have 6 Billion Human Lives on our planet all defined by their DNA that is 99.9% the same in all of us. The only differences which makes us each unique is our appearance, individual interests and talents.
We investigate our universe with our telescopes, computers and intellect and come to the conclusion that 95% of it is unknown which we define as dark matter and energy. When we look through microscopes we discover quantum entanglement and find that Quantum and Relativity can't exist in our current physical model of the universe. The only model that comes close to describing the universe uses string theory and requires at least eight dimensions.
The only rational and logical conclusion is to accept the Unknown and realize that we live in a three dimensional hologram that is part of a much larger unseen universe. Most people believe they can spritually communicate and receive answers, guidance and help by praying and/or meditating. This universe is where our life force is headed when it leaves our bodies.
