@Metal You make some good points but you also bring up a point about the literal vs figurative nature of Genesis. The verse Mark is quoting is Genesis 1:27 "So God created man in His own image; in the image of God He created him; male and female He created them." In this part of Genesis God creates an ambiguous number of nameless male and female humans at the same time.
This part does seem a little weird, but it doesn't necessarily say that he created more than two humans(though it could definitely mean that as well). It does seem to hint that Eve was the first female to me, though. What really gets me is that in Genesis 2:5 it says: "Now no shrub had yet appeared on the earth and no plant had yet sprung up, for the Lord God had not sent rain on the earth and there was no one to work the ground". However, it says that plants came before humans, so how would that work?
You make a great point with the John verses. But the Bible also says a thousand years are like a day to the Lord. Do we accept that as literal?
I think God's just so timeless that saying such a thing just means that any concept of time is just a blink for him, because he's above time itself. Heck, if I've always lived and always will live, then 1000 years would seem pretty short to me too.
