I will explain everything later. Meanwhile, make sure to read the Quran, and compare the Quran to Science (Biology, Physics), Universe....etc, and you will be surprised that the knowledge of DNA, Universe, the whole world has already been mentioned in Holy Quran, were just submitted by Professional with their expertise in the late 20th century.
I know the world is in bad place with full of violence cases, disgusting that is mainly unhuman, and there have been numerous wars. You do know that we are truly blessed, and we are made of clay, (Google it), and Allah instructs Angels and Non Angels to look after human people in Earth, but Non Angels refused as they were made of fire of smoke, valued the status of their better than our, but Angels supported us with the instruction of Allah. Non Angels have refused, and hence, they are devils. They do exists, and only target those who don't have faith or lose faith. Therefore, they can be easily misguided by anyhow (can't be explained). Those who have faith, will always be safe no matter what, and always will be protected no matter.
For what is happening in today world because people have lost the faith, and some people have misunderstood of people doing Jihad or at least that's what gave the impression to the world, and at the moment, they were either taking revenge for whatever reasons. Ever since, there have been wars, based on women, powers, lands, countries,....etc.
Allah has blessed us with many Prophets before Prophet Mohammad (P.B.U.H) with Holy Quran, for the whole mankind, and last messenger of Allah. The reasons the many Prophets were sent because of us, and our wrongdoing that have damanged the world, and misused and abused humanity. The reason for the whatever humanity is left, is because of Islam, is the last source to save Humanity from dying, and bring us to the right path. The example of Holy Kaaba goes way too back, even before Prophet Mohammad (P.B.U.H).
I live in Canada, and i can understand your situation especially athetism people with their contribution for the humanity, but you have forgotten one thing that Allah is the most merciful, and the most beneficient and if we ask forgiveness of our misdeeds, and announce yourself 'There is no God, but Allah and Prophet Mohammad (P.B.U.H) is his messenger', and Allah will forgive us, and grant us to the Jannant. It's never late for those who aren't Muslim.
I will explain better examples of Islam and humanity to restore your lost faith later. Meanwhile, research the Holy Quran to gain better understanding about the Holy Quran.
