if you knew anything about islam then you would know that muslims claim that the quran and claims made within the quran are perfect and valid.
they believe that the quran is a whole, and they challenge nonbelievers to find one mistake because these muslims believe that the quran is flawless.
for a muslim guy to believe that theres even one incorrect claim in the book, the muslims then automatically know and understand that the whole book is invalid.
dont you know muslims believe that God and the word of God is perfect?
there isnt no "oh he really meant to say a sphere but the closest thing to that in those days is an egg" because Allahs perfect knowledge would have said a sphere, NOT AN EGG.
please, in your pm to shoowila, ask him, "when God says something is a thing, such as the earths shape is egg-shaped, can that mean that the earths shape is anything BUT egg-shaped?" and save yourself humiliation.
like many have wished, i wish you a wonderful journey to islam and
back.
