We have seen the effects of a brilliant mind
Joe, I take it you have had tiple or two fueling the burst of wax lyrical.
the extent of the Indus Valley Civilisation shows clearly that it was not only not confined to the Indus Valley
No civilization that I know or very few were ever limited to specific boundaries or certainly not conforming to modern borders. However all had a pivot or
foci from which point in irregular waves they spread out, gradually fading away on the edges. It was not like any had a precise border with a Trumpian wall.
Let's look at Ancient Egyptian civilization which had the Nile as it's foci [analogous to IVC having River Indus] but it spread south into modern Sudan and it's influence extended as far south as modern Eritrea and Somalia.

In fact the Ancient Egytians civilizations spread out from it's foci and permeated south along the Nile to Sudan, Ethopia, Somalia, Eritrea etc. This has given fuel to
Afrocentrism wherein Ancient Egypt is seen as a attempt by Europeans to undo a African civilization by corralling it to the mouth the Nile on the Mediteranean. In other words carving a African civilization into a region and branding it as 'Egyptian' or as a entirely separate entity from rest of the continent.
To my eyes I regard the Indian attempt at diffusing IVC into a sub-continental civilization [I term it Gangacentrism] no differant to Afrpcentrism. Both are attempts to diffuse a regional civilization to a wider geography. If some IVC sites lap over into Afghanistan or India this is no differant from AE sites spilling into Sudan,Ethopia,Eritrea, Somalia etc.
Indeed I would argue that IVC 'fits' into Pakistan far better then Ancient Egypt or even Ancient Greece do with the the modern states mostly associated with them - Egypt and Greece. Note. Macedonia, Turkey and even Albania lay claim to aspects of Ancient Greece. I digress but compared to the 'fit' of Ancient Greece, Ancient Egypt, IVC fits better in Pakistan. 93% of the Indus Valley is within Pakistan. The foci is Pakistan. One look at IVC on a map of India clearly shows that IVC is hanging on the edge with most of India distal. Whereas almost of all of Pakistan sits on the foci of IVC with no location being more then hundred mile from large OVC site.
Why would a farmer or worker want to use a whitening cream,for what purpose?
That was a conspicious example to make my point. It's as obtuse as me asking why would somebody want to look like their summer iterations? And I must add here that people I have seen in UK who tan themselves [tan shops are everywhere] recreate a complexion that is not their normal summer tan but goes well beyond that. Or it would be the colour you would get by sprawling outside almost full on naked day after day in the summer. That is not natural.
And I must reiterate. Lying naked under intense tanning lights in a crazy looking contraption with eye shields, slowly being toasted is, all in a attempt to look like they have been living on sun drenched beaches of Mediteranean is far, far from natural.
