Asa general rule,we accept the simplest explanations of things unless there is a reason not to... The most obvious explanation is that Mohammed made a mistake and the result was the Miriam anachrononism in the quran.
The most simple explanation for Christianity is that people made it up over a number of years, the same for the Torah too. Not only is there no evidence of any miracles there is an embarrassing lack of evidence (for example of slavery in Egypt, and any mass exodus.)
Also, when Jesus apparently rose from the dead lots of pious people climbed out of their tombs and went into the city to talk to people - yet not a single historian recorded this slightly unusual event?
Try applying your "objectivity" to your own religion, Christianity is one million times less credible than Islam due to its extraordinary claims. So, here's the question, which is the most simple explanation?
Scenario A:
There is a God who from time to time intervenes in human affairs on a massive scale, only to then leave without any evidence he was ever there.
He loves some people more than others, to the point that he even wants some people dead, but mostly gets people to kill people, presumably through idleness or inability.
He hated the Egyptians so much he killed them himself by suspending the universal laws of physics in order to drown them....rather than just making them drop dead.
To guide people he incarnated himself as a human.
His mother was a Virgin (what's the religious obsession with women's vaginas?)
He healed the sick, made the blind see, made the disabled walk, cured leprosy, and said "don't tell anyone"
He defied the law of conservation of energy just to create fish sandwiches.
Took a walk on some water just to prove he was god, but was only willing to do it to a few men rather than to everyone.
Got himself crucified.
Rose from the dead.
Rose all the local pious people from the dead so they could tell everyone, but no historian wrote about it.
Instead of showing everyone he was alive, he showed a couple of people and then disappeared somewhere.
And after all this for some reason it is more virtuous to believe without proof than it is to have proof.
Scenario B:
It was all made up over a number of years.
There is a lack of evidence because it was made up.
God no longer appears because.....he never has, it was made up.
God wants us to believe without proof because....people who make up incredible claims cannot provide proof.
Now considering there is absolutely no proof of anything supernatural at all, which do you honestly think is the "simplest explanation"? Are you going to accept the simplest explanation as your general rule, or does it not apply when it comes to stuff you WANT to be true?
And my final question. What is it with wanting to believe despite having no proof? Personally I find gullibility to be an undesirable personality trait, why would God want it? If God wants us to be gullible then we find ourselves in a position where we can believe any old crap; Islam, Hinduism, Mormonism, ad nauseam. Whereas if he provided one single piece of evidence (like an indestructible floating rock with the 10 commandments on it) at least everyone in the world would get a fair chance at getting the religion right wouldn't they?
Yet again if you answer with "because it was made up" it makes sense. You are only required to believe without proof when no proof can be provided. Natural humans cannot produce supernatural events and can therefore not provide proof; so it's no surprise that it is more pious to believe without proof, is it?
Anything that doesn't make sense to you gets shelved at the back of your mind labelled "God will explain when I die". That's crap! If God is perfect then everything would make perfect sense! Take EVERYTHING off that mental shelf you have and write it down on paper. On the right hand side try to write an explanation, see how complicated and contradictory your explanations are. Now write them down again, only this time on the right hand side of the paper write down "Man made it up" and see not only how simple the explanation is, but how it is the SAME explanation for everything. Then you will get your answer!
