W M Sxott disagrees with you. And what is the basis for your opinion that the Earth cooled to below freezing prior to Genesis 1 ? If it cannot be supported by the Biblical text you cannot claim that your hypothesis is implied by the Bible.
As for day length I am not ignoring your assumption - I reject it as a clear falsehood and if you read and fully understood my posts you would know that. The day/night cycle is set up in day 1 and remains in day 4. That cycle is dependent on the rotation of the Earth and therefore it affects ALL the other measurements available at that scale created at day 4. The longer temr measurements (related to the yearly cycle) can't be related to day length without some basis for comparison - you would have to have a measurmeent of the day length BEFORE using it or defien hours based on year length which nobody did. Instead they divided up the day/night cycle - which existed from day 1.
Morevoer even if your claim that new measurements COULD be done were reasonable it is completely illogical to claim that that implies any change in day length.
As to your claim that nobody knows the day lenght that applies equally well to the length of days for the 4th, 5th 6th and 7th days as well as to the year length used ot measure the age of Adam and the other patriarchs. And I bet that you don;t assume that those were significantly better for no good reason - yet you attack me for extending the same reasonign to the earleir days of Genesis 1.
And if I am "acting like a YEC" in refusing to accept your additions to the Bible as authoritative then all I can say is that YECs are right to do so - as an Christian or - indeed, any rational - person would agree.
THe natural reading is that the days and years of Genesis - assumign accurate translation - are not significantly different from our own. If you can coem up with evidence relevant to the reading than I'll listen. But don't accuseme of ignoring facts simply because I don't agree with your unsupported opinions. I really don't appreciate that sort of lie and you would do a lot better to avoid using that tactic.
So lets deal with your arguments:
1 The "revolution" of the sun and moon are the product of the Earth's rotation. It is the Earth's rotation that determines those - and in fact (but not in Genesis) it is that rotation that causes the day/night cycle since the sun is the source of daylight. This point of course has no relevance to the actual poinbt under discussion because what needs to be shown is that a CHANGE in the length of the day specifically at this point is supported by the text (rather than Something Buzsaw Made Up).
2- God's capabilities are not at issue, except perhaps the capability to disobey Buzsaw. I simply point out that there is nothing to suggest a change of day length on the 4th day and that the natural reading is that that "days" really are days. Just like the remaining days and other time units appearing in Genesis.
Finally if we are talking about the IMPLICATIONS of the Bible it must be accepted that additional assumptions are NOT part of those implications. A longer - or shorter day length is not implied prior to day 4 and so anything which requires assuming a significantly longer day length is not strictly speaking an implication of the Bible.
