God's word is infinite wisdom in the finite container of human language. Consider that Christ fulfilled over three-hundred OT prophecies, and how many of His contemporary Jews missed their Messiah? God shifts mankind's paradigms all through history and, we know from Genesis, prehistory.
Creation and humankind's moral fall are points of doctrine that won't bend. We have a reasonable creator who created a reasonable universe. Those with Christian presuppositions have learned creation can be understood through reason. Again, nobody was there to observe these things and these space time events. They're being interpreted to us in a dead language, by a man halfway across the planet 5000 years away in time. Inspired or not, understanding Moses' wisdom is a real challenge.
Forcing doctrinal events into a young Earth age makes two assumptions not backed by Scripture. Adam & Eve's fall took place:
1) on Earth, and
2) in this dimension.
Stay with me now . . .
The Bible was supposed to crack if our Sun was not the Universe' center because that's how Moses' creation story was interpreted. The Heliocentric theory of the universe was disproven, and Scripture still stands.
Check Strong's Concordance for the word "Worlds." It's used in the sense that this huge universe may not have been created for just for Earthlings.
- What about Genesis 5:1-2? Did God create more humans after Adam and Eve?
- What about extra-dimensional beings mating with human women?
- Genesis 6, the Great Flood, wiped out the Nephilim.
- People used to live for hundreds of years.
God's acted into space-time creation with huge change—at the fall, and the flood. Every time we get God figured out, He shifts another paradigm. Let's choose our dogmatisms very carefully.
