This is from a question on Quora I answered. It will not post unless accepted. So I posted it here as a preventative measure to save my content from disappearing.
The List Answer: There are a few reasons why war will stop regionally or world wide. But, from human history there and always have been wars every where. #1. Unable to fight anymore because of the lack of manpower or weapons. #2. No will to fight. #3. So called peace agreements which are temporary. #4. All sides have physically destroyed each other. #5. Extinction #6. All of humanity begins to live their lives as the prophets have taught.
Evolving Answer: All of humanity does not need to evolve in anyway to achieve true and real peace. All humanity has to do is freely choose to live in a good way as which has already been taught to humans in ancient religious texts. Humanity needs to stop believing lies as truths and truths as lies. Like the idea of the races of humanity is a falsehood believed as a truth. Even while the scientific truth from 2003 was evident from the Human Genome Project which concluded that all of humanity is more than 99.9% genetically the same. The math which supports this one conclusion is very strong at more than 99.99% certainty. The differences we see in each other is in the remaining less than .1% of our total human DNA.
Peaceful Extinction Answer: True and real peace can only come two different ways. They are by all humans making good choices by their own free will and through the conclusion of the extinction process. There is peace on Mars, Mercury, Earths Moon, Venus and everywhere else in the universe which is devoid of any life. The Earth will also have peace when all life on this planet is erased and this is prophesied in the Holy Bible when all of the waters and air of the first heaven is removed. When the entire planet is purified by fire. I believe these actions will be done by God because while humanity is destroying and killing each other more and more efficiently with each new war. Humanity ends up causing so much harm to the planet that the only way to cleanse the planet is with fire. A force of fire so powerful that all of the water and air is removed from the planet AND IT IS ALL OF HUMANITIES FAULT. All of the life on this planet dies because of humanity. Humanities suicide also kills everything else.
Good Peaceful Answer: The prophets have already came to teach the basics of how to truly live our lives. The ancient religious texts taught us how to live our lives and how to not live our lives. Each of the major religions in the world toady can be summed up into one basic word each. These basic words are Love, Peace, Harmony and Life. It is easy to see how every religion has really messed up the world and this is because of self serving leaders throughout human history. But, never the less the fundamental purpose of each religion teaches these things and are real spiritual truths. Despite how the religions are today. If your religion or sect or denomination practices contrary to the basics then your really the worst kind of human follower.
1). To LOVE one another. Even your enemy. This means that all of humanity should love each other, serve each other, take care of each other, be compassionate and merciful to each other. It is really that simple as all of humanity is a singular family or as the native indigenous tribes of Turtle Island have always said that we are all of one relation. So no matter how any other appears to you. Your all directly related. We are all brothers and sisters to each other.
2). To Live in PEACE with each other. We are all supposed to be peaceful to each other and not seeking out argument, fights or conflicts. It is really that simple. But people have to learn to love peace. This is how peace on Earth will benefit all life on this earth when humans want to be at peace with themselves. This is a free choice.
3). To exist in HARMONY with all things. The entire planet can exist in harmony as humans were meant to be the caretakers of this planet. This once humans grow in sufficiency they will bring all of the good things to other planets in the solar system and in the galaxy. Can you imagine the power of harmony in all aspects of life and what it can do for all of humanity? But, humans need to know, understand and love what harmony is. Without a fundamental love for harmony in each individual human life. This planet will die. This is really that simple.
4). To cherish all LIFE. No matter how small or how large any life form is. Life should be loved. All of humanity should cherish that life as something which is uniquely important. The killing of babies should sadden you. Life is an important quality which enables the opportunity of harmony to happen.
Simple Summery Answer: To achieve peace on Earth each human being must freely choose to love love, love peace, love harmony and love life. These principles are the pathways to a real and genuine living peace which can be experienced while humans are not extinct. How do you want your peace alive or dead? These two choices are what is prophetically coming for all of humanity and for this entire planet very soon. Either way it is your individual human choice.
To avert all of the coming bad and sad prophecies. We each must decide to do the following everyday, every hour, every minute and every second.
