Most major Biblical scholars accept that Exodus was written during the Babylonian captivity. I still find it amazing you go into a place like GNC, take full advantage of modern science, nutrition and supplementation and believe in Bronze Age fairy tales. I just can't wrap my head around it. 
Define "major", as I can give you plenty of Biblical scholars, who state that Exodus was written far earlier, by Moses.
Of course, there's the little matter of a certain 1st-century Jewish historian (Josephus), who cites Moses as the author of the book of Exodus.
As for your GNC comment, the reason you can't wrap your head around it, is because your head is loaded with the foolish and woefully inaccurate BELIEF that scientific advancement (and reaping the benefits, thereof) require a rejection of one's Christian beliefs.
Of course, you keep forgetting that the process, which makes the whey protein and chicken breasts that you consume, safe to eat came from a man, who not only believed in God, but who also completely dismantled a godless tenet as to how life developed.
If you enjoy mass-production of literary works in the Western world, you can thank the man who developed the movable-type printing press, making the Bible among the very first mass-produced works, so that people could read Scripture for themselves.
Loco has done this more times than I care to count; but, I'm sure he'd be more than happy to refresh your memory about the Christian men, who contributed to the fields of medicine, curing some of the deadliest diseases on the planet. That doesn't take into consideration that many hospitals and humanitarian centers were founded (and still run today) by Christian men and women.
Science is simply the study of nature....God's nature. The more discoveries (finding what was already there) I see, the more I'm convinced that this planet, even in its sin-altered state, has Divine origin.
If anything, YOU shouldn't be taking advantage of modern supplementation. If you don't believe in God, don't eat His chicken or cows. Don't consume the milk (or product made from such) from His cattle. Leave His wheat and barley, fruits and veggies, alone.
