I think this is too close to a religious argument and not appropriate for the boards.
As for why wheat intolerance is more common now... well I explained that already. It is both more recognized and diagnosed now and much more actual occurences I feel due to something in the wheat supply. I am not an organic whiz but it doesn't take hard science to realize the way food is produced now a days with all the genetic engineering etc could lead to many health problems. There is also a huge increase in autism as well which some feel has a common explanation.
And if mankind cannot digest wheat since it is a 5000 year old introduction, then why were they not more intolerant of it in the beginning of eating it? That would make sense and would have made humans stop consuming it had the manifested symptoms of GI. But by that theory (about wheat being a problem because it is new) all the grains would be hard for us to digest because as you say, humans did not farm those other grains before 5000+ years ago either. And tomatoes would be awful for us too since we have only eaten them for 300-400 years. You see what I mean. Wheat is indeed hard to digest and many are allergic or intolerant, but the theory of it being new to mankind being the reason for intolerance just doesn't make sense. It also is not the purpose of the boards to talk about human history.
In summary, if we are not 'used to' wheat yet and need more time why are people becoming less able to eat it than previously and not more adapted to it? It is true for both wheat and dairy that humans have become less able to handle them over time and not more so. Does it not seem more reasonable that there are deeper reasons why so many people have GI problems now a days?
