Definitely do not discuss any of this.
Did anyone notice the little girl roasting peanuts on a lattice bamboo construction over a fire (bamboo takes longer to burn) and a lack of matches and wonder how she managed to know that?
What about the handmade woven beds and screens?
How about wondering about how to maintain morale with games and music?
Or dealing with human waste?
Personal cleanliness?
Shelter?
Is this not partly what Bushcraft is about?
Some people cannot see the woods for the trees!
It is very unusual for people new to a subject to have a broader view than those who have been interested/involved for longer. Those links I posted, and some other reading you might do here, would give you a better view of the scope of the "wood".
Wondering how people know how to do things might be interesting, but it is usually a fruitless activity unless someone has recorded it, or you make it your special field of study. How did the Kalahari Bushmen first find the use for the grubs that feed on Comiphora bushes? Who figured out that you can change the properties of animal hide by rubbing brains over it, and smoking it? Where and when was the hand drill first used to make fire? There are endless questions like those, and while the answers may be out there, we are unlikely to approach the truth without focused and in depth study. Some are most likely to be unknowable.
I think your original question was along the lines of, "Is living in an Indian refugee shanty village = bushcraft because of the primitive conditions?" Sure, you are welcome to draw parallels, but don't be surprised if other people disagree. A lorry driver using a trucker's hitch to secure his load isn't practising bushcraft, using a map and compass to navigate central London isn't bushcraft (although Corbett applied his jungle honed skills to urban navigation), paddling a canoe isn't bushcraft, making an all wood longbow isn't bushcraft, if I use fatwood from Orvis to light my wood stove, that isn't bushcraft. However, all those skills and activities are considered by many to be related to or part of "bushcraft".
Another example. Is melting some old bits of poly rope or smashed up plastic = bushcraft? Is using hot-glue = bushcraft? Standing in my nice warm workshop, using hot glue to assemble some crafting or camping gear? What if the hot "glue" is made of that plastic scrap? If that is bushcraft, then the word has no specific meaning any more. If that is not bushcraft, does changing one's physical location make it bushcraft? Not bushcraft standing in my living room, my back garden, down the street, in the local woods...? What about on holiday? Does it become bushcraft if I have darker skin? So why would it be bushcraft it someone in Miri (Malaysia) uses melted Bic lighter bodies to glue on a parang handle? Just because they are geographically and ethnically closer to people who until recently used tree resin to do the same job? The person knowing what tree, how to collect, process and apply the sap, that would be bushcraft. Reading about it in a book and going and vandalising one of Kew's specimens...not so much, but arguably more than the melted plastic guy.
Of course, you might have been asking "Can bushcraft skills be applied to living in an Indian refugee shanty village?", in which case the answer is a simple "yes, of course". More complicated though since the best bushcraft skills in the world do not mean that you or your group will be able to cope with shanty town life all that much better. The Penan of Borneo are a good example. Living as jungle nomads their skills were legendary, however, the Malaysian government made a big push to get them all settled into permanent villages. Adjusting to village life has not been easy. Living by in the jungle they didn't have to worry about waste build up, everything was biodegradable and rotted to nothing, they moved on anyway. No real problem with managing water for washing, cooking, cleaning and waste. In a fixed village, exposed to the outside world, waste builds up, plastics and metals do not degrade, plants that are cut don't have months or years to regenerate New skills, non-bushcraft skills, are needed.
