KEMARIN SORE aku sempat ngeliat debat antara 2 orang Iraq mengenai apakah bumi itu datar atau spherical.
Pengusung keyakinan bhw bumi itu datar seorang yg Iraq yg sudah berumur kira2 60 th dg gigih menyatakan bhw pengetahuan apapun yg tidak didukung oleh ayat2 Al Qur'an mustahil benar. Orang ini a.l. menyatakan bhw bulan itu garis menengahnya setengah dari garis menengah matahari! Dia haqul-yakin bhw bumi itu datar (spt tempat tidur orang2 Bedu - yaitu sajadah yg digelar di pasir) krn itulah yg dinyatakan oleh Aulloh dlm Qur'an. Mengingat Qur'an tidak banyak menyebut ttg banyak cabang dari science maka orang ini tentunya percaya bhw listrik itu sebenarnya tidak ada, begitu juga pesawat terbang, shuttle, telephone, internet, bahkan internal combustion engine dan mobil dan ratusan ribu hasil penemuan Kafir yg apparantly Aulloh totally missed.
