Manbags are just a fairly clever marketing name to make it easier to sell handbags to men as well as women - a straightforward expansion of the potential market.
oh rly??
Yes, really. Your snippet about the earliest recorded bags is interesting, though it's almost certain that people were using bags long before recorded history. A bag is so useful in a hunter-gatherer society, especially for foraging, and so easy to make that it would be strange if people were not using them tens of thousands of years ago.
However, people are talking about a specific kind of bag - a modern handbag.
If I was in the business, I'd be doing the same. Handbags can be fantastically overpriced and still sell. The markup on a handbag can easily be an entire order of magnitude greater than on other bags. It therefore makes sense to try to extend the handbag market to men - you (generic) can potentially double the market for your most profitable products.
EDIT: Given all the blather about homosexuality and the responding blather about men being insecure in their sexuality, blah blah blah, I'll throw a spanner in the works. I'm bisexual. I have been known to parade around in lacy frippery and fishnets with high-heeled boots, strutting my stuff at some quite outrageous "gay"(*) clubs. I think that should establish my credentials as not being a man who "doth protest too much" about his heterosexuality. I don't care if some men wear handbags. I don't care if they're straight (unless I fancy them, in which case it's a disappointment, obviously) and don't assume that carrying a handbag necessarily indicates that a man is gay. I do, however, recognise an attempt to sell handbags to men and I can deduce the most likely reason why (profit).
* "gay" rather than gay because they weren't restricted to homosexual men, or homosexual people in general. I wouldn't go to a "no straights here" club, because I think it's discriminatory.
