You need facts not fiction.
What has caused our disagreements and arguments? Our problems stem from ignorance and they continue because of ignorance. Other defilements such as wanting possessions, power and position over others also play a big part.
Primitive man was ignorant of the causes of the elements that controlled his survival. Animism was an attempt to explain, the sun and rain and all the elements affecting his survival. This gave birth to shamans and witch- doctors, clever, devious people that claimed they could communicate with the e spirits world. This gave them standing and power in the tribe.
This was in the time of the hunter gathers as man progressed to domesticating animals and cultivating crops he became less nomadic. Villages grew and man became more reliant on the clever ones to lead them.
Cities and civilisations were formed. A clever leader created gods and raised taxes to build temples and idols of their gods. Many gods were created to meet all occasions. A hierarchy of priests invented dogmas controlling the people with fearful gods. Sultans and kings consulted the priests on how to manage their people.
Having many gods caused discord in the community, as it does to this day. Abraham united his people by giving them a vengeful jealous all powerful god that would not allow worship of other gods. Although the Jews were his chosen people they have been homeless and persecuted throughout history.
Strong walls were necessary to protect crops from animal invasion backed up with armies, to protect the wealth of prestigious rulers and their religious priests. Many rulers were psychopaths. All were sick some proclaiming Divine right some claiming to actually be gods. Greed ruled as it does to this day. Greed goes with ignorance, as wisdom is followed by peace and contentment.
Knowledge is not synonymous with wisdom, knowledge gave man bronze, iron, steel, gunpowder and the atom bomb. The technology we have today all came from knowledge. Technology allowed the powerful to invade, plunder, dominate and take control of other countries. Technology correctly used benefits man, but the ignorant abuse it. Wisdom must be practiced in the use of technology.
That very brief outline of the history of man, if taken seriously and followed up by diligent research, from proven sauces, will contribute to enlightenment. Feeding the mind on nourishing wholesome food is the way to bring peace into our life. There are still foolish people that believe witch-doctors and cunning leaders. These gullible people are not evil it is what they accept without question that is evil.
