God meant he created the earth in 24 hour days.

1. There are no exceptions to this rule. Wrong. There are exceptions. 'The first exception to the "rule" is found in Genesis 29:20, where echad yom refers to a period of seven years that Jacob served Laban to obtain Rachel. In the book of 1 Samuel, David says that he "will perish one day [echad yom] by the hand of Saul."Obviously, David was not expecting to die in exactly 24 hours. In fact, David was never killed by Saul, but died of old age many decades later.' 'A prophecy from the book of Daniel describes the demise of the ruler of the Syrian kingdom, Seleucus Philopator, the Son of Antiochus the Great. According to Daniel 11:20, "within a few days [echad yom] he will be shattered." There are several examples where echad yom refers to the Day of the Lord - a period usually interpreted as being seven years in length.Specific examples that specify a period of time longer than 24 hours include the following: 'For behold, the stone that I have set before Joshua; on one stone are seven eyes. Behold, I will engrave an inscription on it,' declares the LORD of hosts, 'and I will remove the iniquity of that land in one day [echad yom]. 'In that day,' declares the LORD of hosts, 'every one of you will invite his neighbor to sit under his vine and under his fig tree.'" (Zechariah 3:9-10) For it will be a unique day [echad yom] which is known to the LORD, neither day nor night, but it will come about that at evening time there will be light. And it will come about in that day that living waters will flow out of Jerusalem, half of them toward the eastern sea and the other half toward the western sea; it will be in summer as well as in winter. (Zechariah 14:7-8) "He [the Lord] will revive us after two days; He will raise us up on the third day, That we may live before Him. (Hosea 6:2) 'If we are to interpret echad yom as referring only to a 24 hour day, then people will only be able to invite their neighbors over during one 24 hour period of time. Obviously, Zechariah 3:9-10 refers to an extended period of time. Later in his book, Zechariah describes this "one day" as being "in summer as well as in winter." This verse clearly indicates that this "one day" must be at least six months in length. The third example above is somewhat difficult to interpret, but is often interpreted as representing long periods of time. Gill's commentary says,"...these two and three days may be expressive of a long and short time, as interpreters differently explain them; of a long time, as the third day is a long time for a man to lie dead..." These six examples clearly establish that when yom is used with a number it does not always refer to 24-hour days.' [4] [4] http://www.godandscience.org...2. I addressed this within objections 3&63. The changes made to the calendar from time to time through the centuries has not affected the weekly cycle of seven days.If you read the creation account, there is no reference to the end of the seventh day. On every other day, there is "evening and morning, day 'n'." The bible even tells us that the seventh day continues into the present:'For He has said somewhere concerning the seventh day: "AND GOD RESTED ON THE SEVENTH DAY FROM ALL HIS WORKS"; (Hebrews 4:4)Therefore let us be diligent to enter that rest, so that no one will fall, through following the same example of disobedience. (Hebrews 4:11)'We cannot enter God's seventh day of rest unless it continues to this day, since we were not alive during the first 24 hours after the sixth day. If God's seventh day of rest was 24 hours long, than the author of Hebrews is telling us to do something that is impossible. This is just another example of the problem of assigning each creation day to 24 hours.'[2] http://www.godandscience.org...4. If the third day is actually a long period of time, how could plants have existed without sunlight?This is because Pro's interpretation of those verses are inaccurate. For instance, the Hebrew phrase translated "heavens and earth"(ha"shamayim we ha"erets) refer to the entire created universe [1]. This Hebrew phrase (known as a merism) means "all the raw materials needed to make sun, planets, stars, nebulae, galaxies, molecules, atoms" or "the entire universe"." So God created the entire heavens and earth at the beginning of the first creation day, which would include the sun and moon.' [1] http://www.godandscience.org... 5. The word "remember" at the beginning of this commandment cannot have meaning if the days were long eons of time (much longer than human lifespans). The admonition concerning days of labor and day of rest would also be meaningless.Let us not forget that God also declared a Sabbath for the land, which consists of six years of cultivation followed by a seventh year of rest:"Speak to the sons of Israel and say to them, 'When you come into the land which I shall give you, then the land shall have a sabbath to the LORD. Six years you shall sow your field, and six years you shall prune your vineyard and gather in its crop, but during the seventh year the land shall have a sabbath rest, a sabbath to the LORD; you shall not sow your field nor prune your vineyard.'" (Leviticus 25:2-4)'This text establishes the principle of six periods of work followed by one period of rest. And in this case, the "days" are one year long. As Christians, we recognize that man's Sabbath week represents the one in seven principle, since we do not rest or devote the actual Sabbath day (Saturday) to worship, but usually do so on the first day of the week (Sunday, the Lord's day). If we insist upon taking this verse concretely, we would have to start worshipping on Saturday only. [2] 6. Such expressions as "day and night," "evening and morning," "light and darkness" can hardly be understood as indefinite periods of time.First off, days and nights were clearly created on the fourth day.Secondly, Not all the instances of "morning" and evening" refer to a literal period of time. Here is an example from Moses:In the morning it [grass] flourishes, and sprouts anew; Toward evening it fades, and withers away. (Psalm 90:6)'This verse refers to the life cycle of grass (compared to the short life span of humans). Obviously, the grass does not grow up in one morning and die by the same evening. The period of time refers to its birth (morning) and its death (evening) at least several weeks later.'The first thing one notices when looking at Genesis 1 is the unusual construction surrounding the words morning and evening together with day. This combination is very rare, occurring only ten times in the Old Testament, six of which, of course, are in the Genesis creation account. The remaining verses (NASB) are listed below:Now on the day that the tabernacle was erected the cloud covered the tabernacle, the tent of the testimony, and in the evening it was like the appearance of fire over the tabernacle, until morning. (Numbers 9:15)"For seven days no leaven shall be seen with you in all your territory, and none of the flesh which you sacrifice on the evening of the first day shall remain overnight until morning." (Deuteronomy 16:4)"And the vision of the evenings and mornings which has been told is true; but keep the vision secret, for it pertains to many days in the future." (Daniel 8:26)'The first two verses obviously refer to 24 hour days, since this is readily apparent from the context. The fourth one refers to many evenings and mornings, which "pertains to many days in the future." This verse actually refers to events that are yet to happen, which is 3000 years of days from when it was originally written. Therefore, One could easily say that these mornings and evenings represent thousands of years. However, none of these verses have the form which is seen in the Genesis account.'[3][3] http://www.godandscience.org...
