From a grammatical reading of the text , it is clearly understood as creation in six earth rotation , 24 hour days .
Mr Pattle Pun , who is a biology and chemistry lecturer at Wheaton College , illinois , accepts exactly that . But has rejected it's true meaning and instead has applied evolutionary science to the text and eons of time .
Mr Pattle Pun :
‘It is apparent that the most straightforward understanding of Genesis, without regard to the hermeneutical considerations suggested by science, is that God created the heavens and the earth in six solar days, that man was created on the sixth day, and that death and chaos entered the world after the fall of Adam and Eve, and that all fossils [sic — creationists would say ‘most’] were the result of the catastrophic deluge that spared only Noah’s family and the animals therewith.’
Pun, P.P.T., Journal of the American Scientific Affiliation 39:14, 1987;
‘It is of course admitted that, taking this account [Genesis] by itself, it would be most natural to understand the word [day] in its ordinary sense; but if that sense brings the Mosaic account into conflict with facts, [millions of years] and another sense avoids such conflict, then it is obligatory on us to adopt that other.’
Hodge, C., Systematic Theology, Wm. B. Eerdmans Publishing Company, Grand Rapids, MI, USA, pp. 570–571, 1997;
Luther said :
“When Moses writes that God created heaven and earth and whatever is in them in six days, then let this period continue to have been six days, and do not venture to devise any comment according to which six days were one day. But if you cannot understand how this could have been done in six days, then grant the Holy Spirit the honor of being more learned than you are. For you are to deal with Scripture in such a way that you bear in mind that God Himself says what is written. But since God is speaking, it is not fitting for you wantonly to turn His Word in the direction you wish to go.”
