Sometimes that thought hits me. I'm still a young apostate. If I am wrong, then I guess I'm going to hell. But I am wrong, then a lot of people are going to hell. I still have a hard time believing this. I really want to believe that most people will go to heaven.
Like I said earlier, make sure you have turned every stone you can. Examining theology, anthropology, science and the huge variety of religions should be a good starting point.
But polytheists and atheists are going to hell. And honestly any other religion other than Islam seems to leave you in hell. I am not sure I could live with myself in heaven, knowing a majority of all people are burning in hell. The 100 000 years of homo sapiens*. And all the other hominids. All people before Islam, and after Islam until the end of time.
Islam does have a take on this, so let me play devil's advocate here and say that in Islam prophets were sent to every nation and tribe throughout history with some form of monotheism. It's the people who have corrupted the primordial faith. Islam is the "final" religion and abbrogates all the previous messages. The "ummah" of those messengers who followed those messages correctly will go to jannah and as for those who didn't get the message, Allah will judge accordingly. If people have had a distorted view of Islam, then they will not be punished.
The flipside to this is, is to read the history of world religions and see empirically what has happened and also to study anthropology to check if it confirms what Islam is telling us.
Not to mention that Allah has let people kill in his name for ages and not intervened. If people were committing atrocious crimes in my name I would shout out from the highest roof top and command them to stop.
What about free will?
I just can't believe if there is a God out there, which is becoming harder and harder to believe, that he would be the God of The Bible and the Quran. His mentality and personality in those books reflects more closely the mentality and personality of people of that time. And not of ours. In fact the morality and science and knowledge in the those books should be unmatchable. For all time. But its not.
Your first remark "I just can't believe if there is a God out there", is where you should concentrate your study on (if you have not already done so) once you have established to yourself that he doesn't exist, then pondering about the Quran or Bible is superfluous.
Lets take an example, Lord of the Rings, Dan Brown and Harry Potter. These books are the most popular thanks really to great story telling and word of mouth.
If the Quran really, really, really was the word of God, it would incontestable, everybody would be a muslim. This is not the case.
This is where the element of "faith" comes in.
Sorry, for the rant, I have to write like this in order to fight doubt and fear. Rationality puts fear back in its grave.
Not to worry and stay well.
