I cant see, hear, smell, taste or feel God.
Therefore I conclude - Not real.
Neither can you see, smell, taste or feel... your brain. That clearly doesn't exist then?
@ Neil -
You keep raising the same point over and over, and if I try to view things from a non muslim mindset I do understand your question. However, you need to try and look at this from the mindset of someone who believes in God.
You have stated over and over that your circumstances have made it impossible for you to believe in God. Your circumstances are a hell of a lot better then the majority of the people in this world, therefore first and foremost you have so much to be thankful to God for, because as you have repeated many times... you had no say in the circumstances you were born into. I have no doubt that there is something stopping you from believing in God, but all your questions are actually answered in the Quran itself.
It is true that everyone is tested differently, however God never places a burden on a soul greater than it can bear. Some people are weaker then others, some are stronger, some have more compassion in their hearts some have less. God alone is perfect, and He alone will judge between His creation.
002.118 (Quran)
YUSUFALI: Say those without knowledge: "Why speaketh not Allah unto us? or why cometh not unto us a Sign?" So said the people before them words of similar import. Their hearts are alike. We have indeed made clear the Signs unto any people who hold firmly to Faith (in their hearts).
PICKTHAL: And those who have no knowledge say: Why doth not Allah speak unto us, or some sign come unto us? Even thus, as they now speak, spake those (who were) before them. Their hearts are all alike. We have made clear the revelations for people who are sure.
SHAKIR: And those who have no knowledge say: Why does not Allah speak to us or a sign come to us? Even thus said those before them, the like of what they say; their hearts are all alike. Indeed We have made the communications clear for a people who are sure.
(3 translations of the same verse)
There are verses already stating the excuses that people will use once the reality of things becomes apparent to them. It tells you what the signs of God are, and how to remove the veil over your heart which is blinding so many people. You need to read the english translation of the Quran fully, with an open mind (not having made your mind up before you touch it), and God willing all your questions will be answered.
The question in this thread is not about Muhammed pbuh waging war on the unbelievers or marrying Ayesha, it is the validity of his claim of being a prophet of God. That is the only thing being disputed really because if you believe in Moses, Noah, Soloman, Jesus, Muhammed peace be upon them all, then you know whatever they did was commanded to them by God therefore you have no hesitation in accepting it.
If you knew without any doubt that God existed, if you knew this, and you knew they were His prophets, you also would not dispute anything they said or did.
