How can Allah make so many mistakes in Qu'ran??? or it seems Mohammed lied??

Muslims tend to close their eyes to all these inconsistencies and despite them accept this book as a miracle, just because Muhammad said it is. Far from being a miracle, the Quran is one of the stupidest and confused books ever written. Quran contains many scientific, linguistic mathematical, logical and historic errors. We may not be able to see what is going to happen after we die and whether those outlandish claims of paradise and hell are true or false, but we can easily see that the Moon is not above the stars as the Quran says, the mountains are not pegs to hold the Earth from shaking, the sky is not a dome sustained by invisible pillars, the stars are not lamps to adorn this dome, the sun does not set in murky waters, the tale of the foetus as explained in the Quran is nonsense, the fractions given by Muhammad to divide the inheritance do not add up, Mary the mother of Jesus was not the sister of Aaron and Moses, and countless other statements of the Quran are false.
