Reasons why people choose to be Muslims

Wa'alaykum salaam,

Assalamualaikum I am a practicing Muslim and recently I have begun questioning to myself why I chose to be a Muslim over other religions. Truth be told I only followed Islam because I was brought up in a Muslim family and hence I never questioned. I am not the most intelligent person and failed in education. I understand the Quran is seen as a miracle with lots of scientific, historical facts and unrivalled use of linguistic devices and is usually the main reason why most people accept Islam. However, when I question any Muslim friends, family or peer they don't really understand the science or history of the Quran and can only point to online sources mostly written by other Muslims. Now, I tried reading these online sources and I find understanding them too difficult and very hard to read for extended period of time (mostly because my mind just wonders off or gets bored no matter how hard I try). In addition to this I can easily find other sources written by people from other faiths rebutting these statements, which are equally difficult to understand; as I have stated I am not the most cleverest individual. Being incapable of understanding either sources how can I decide which is correct and which is wrong. Most articles are written by experts in their field who have possibly studied years in to these subjects, who am I with limited knowledge to say they are wrong. Currently I simply believe articles in favour of the miracles of the Quran simply because I am a Muslim or it was written by a Muslim. I am sure the average Muslim are very similar to me and also would favour material defending the integrity of the Quran, that is because most people lack the expertise to understand complex scientific concepts or even understand Arabic (let alone the Quranic Arabic); therefore simply agree with the material that suits their belief system. Correct me if I am wrong but doesn't that imply that only people of knowledge can truly find the correct religion as they can filter through all the myriad of information available to conclude which is the correct path to God. However, if we look at our world we see that even amongst the greatest most knowledgeable people there are disagreement. As a consequence the average individual with the average knowledge are expected to dig through the materials written by others and try to understand and come to a conclusion on whether it is correct or not. How can we then blame each individual for not finding the correct path or going astray; as it is difficult to find the correct path to the correct religion when we can barely understand what we believe in. I understand that the Quran is supposed to be the guide for humanity sent by god, but can we truly say that this is the best guide god could have sent to us. Most Muslims don't understand the Quran at a deeper level i.e. The context, meaning and etc. Instead we rely on Scholars who may have biased views to tell us these meanings. We know that humans can make errors and this can lead division amongst Muslims and create extremists that hijack the religion. If the Quran was truly the best guide that God could have given us then why is it so unclear. I find it strange that the Quran fails to mention basic fundamentals of Islam such as how to perform Salat, Wudhu (ablution) or how to calculate Zakat. So I guess my point is how can I determine for myself If Islam is the correct religion and the others are wrong, without understanding all these complex science, history, philosophy, Quran literature etc. Or do I just continue to believe like a sheep with no strong foundation for my belief. Ultimately, I am confused and unsure why I am a Muslim, I truly believe Islam is the correct religion but it would be hypocritical of me to simply believe in Islam out of gut instinct; as anyone from other faiths can use the same reason to believe in their religion. For these reasons I sometimes start to think is Islam just another religion and I am just a follower of it as a Christian is a follower of Christianity, etc. If so how do I know who is following the correct religion? Its easy to look at a material showing inaccuracies in the bible and to conclude that Christianity is false, but then disagree to an material citing inaccuracies in the Quran without even having any way to rebuttal the claims. I am sure many people reading this Post do understand the Quran, have strong understanding of science, the History of the Quran and more. However, I ask you to remember not every Muslim possess the same Intellect and therefore may simply be following Islam ignorantly. Please answer my question with that in mind.
