Chapter 41 Verses 9-12
Original text
  • Disbelieve ye verily in Him Who created the earth in two Days, and ascribe ye unto Him rivals? He is the Lord of the Worlds.
  • He placed therein firm hills rising above it, and blessed it and measured therein its sustenance in four Days equal, for (all) who ask;
  • Then turned He to the heaven when it was smoke, and said unto it and unto the earth: Come both of you, willingly or loth. They said: We come, obedient.
  • Then He ordained them seven heavens in two Days and inspired in each heaven its mandate; and We decked the nether heaven with lamps, and rendered it inviolable. That is the measuring of the Mighty, the Knower.
Problem It is argued that the Arabic word translated here means periods of time rather than days. If this is the case then we do not know how long each period of time is. If the periods of time are the same then the Earth would have existed for at least 50% of the life of the universe. The same word is used elsewhere in the Quran to literally mean an Earth day[1] If the length of each period is different (the only way to save the existing text) then mentioning the number of periods is uninformative, superfluous, and irrelevant; and the word equal is misleading. It is for these reasons that mentioning the periods of time is irrelevant and unnecessary, and makes the Quran resemble the incorrect creation story of Genesis.
Solution Remove any mention of the amount of time taken to create the Earth and universe.
