Monotheism since ancient times

[Hayalilaydaa]

Selamu aleykum guys ive just came across a articel showing Belief in one god has been there since sncient times yet still in wikipedia for example it still says it derived from the ancient israelites which supposedly worshipped one supreme but others too? i know its not true ive read the article from submission.com but he/she just mentions some archealoges (? Idk how to write it english is my fourth language) and well te books theyve written but other than that they dont show evidence no pics etc. Does any of you know HOW they found out about the fact that they believed in ONE

Prophet Adam was Muslim. All prophets were Muslims. We don't expect rocks, idols or stones with the picture of God to be found because Muslims believe that God isn't like any of his creation.

Many people have the misconception that Islam started about 1,420+ years ago, and that Prophet Muhammad was the founder of the religion of Islam. In fact, Islam existed since man first set foot on this earth.

“Submission” to God existed since man first set foot on Earth. Muhammad isn’t the founder of Islam, but the last and final messenger of Islam. The word “Islam” was first revealed to Muhammad by Allah, but the way of life of ”submission to God’s will” existed since time immorial. Hence, all Prophets of Allah submitted their will to God and abided by the laws which they had to follow. They all preached this fascinating way of life of submission to God.

Well. the concept of monotheism was always there. you'll never find manuscripts proving any ancient person let alone a Prophet from 4000 years ago. thing is. noone really recorded their history,

They were passed on generation to generation. their stories.
