Some irrefutable Facts in Life are:
God exists.
The Universe was not created, and is infinite and eternal.
Everything evolves. Which is how the Universe works.
The Universe creates all things, besides Itself, matter, space, and energy.
Which are the most fundamental things that the Universe is made up of.
Time is not a thing, itself, but just a name used to describe a human behaviour.
There is only one Mind.
The fundamental reason all human beings think and do what they think and do is past experiences.
APE-thinking is why human beings take and took so long to uncover the actual Truths in Life.
The belief-system is why human beings do not move forward in learning and understanding.
The youngest human beings are the most intelligent human beings.
Adult human beings can and do learn and understand far more about what is actually Right and Wrong in Life from younger human beings than they ever had from older human beings.
How the Mind and the brain work is the Mind is always open, and sees and knows everything, the brain, in conjunction with the belief-system can be closed and can see and know nothing. The brain gathers and stores information, which becomes knowledge, which when presumed or believed to be true can and does prevent and stop the Truth from becoming known.
Living in Peace and in Harmony with everyone, as One, is far simpler, quicker, and easier than you human beings imagine, in the days when this is being written.
To learn and know, for sure, all of these Facts, one just needs to become more open, more honest, and be willing to change for the better.
