In speaking about marriage and divorce, Jesus takes the Pharisees back to the beginning in Mark 10:6 (NKJV, emphasis mine):
"But from the beginning of the creation [αρχης κτισεως], God ‘made them male and female.’"
The Greek phrase αρχης κτισεως appears in two other passages of Scripture (NKJV, emphasis mine):
"For in those days there will be tribulation, such as has not been since the beginning of the creation [αρχης κτισεως] which God created until this time, nor ever shall be." (Matt. 13:19)
and saying, "Where is the promise of His coming? For since the fathers fell asleep, all things continue as they were from the beginning of creation [αρχης κτισεως]." (2 Pet. 3:4)
In Mark 10:6, does "the beginning of the creation" refer to the creation of the Universe? If so, does Jesus' placing of the creation at "the beginning" suggest that humankind was created during the beginning of the Universe? To explain, within the interpretive framework of a literal week, Day 6 (or any day for that matter) could easily be called "the beginning of the creation." However, if the days involved ages of time, Day 6 (when mankind was created, Gen. 1:26-31) would seem to be many ages after "the beginning of the creation," placing the day more toward recent times.
Does Jesus' language, therefore, imply a short, literal creation week in which even Day 6 happened toward "the beginning of the creation"?
Note: In keeping with the policy of the Hermenutics Stack Exchange, this question is not about whether the earth is old or young; I'm not even asking whether the Bible teaches that the earth is old or young. Instead, I'm asking if Mark 10:6 in particular implies a literal creation week with its quotation from Genesis 1:27 (which, in context, is Day 6), a verse Jesus says happened at "the beginning of the creation" (NKJV).
