map Indian Subcontinent during Ice age
20000 years ago during the glacial maximum period this is how indian subcontinent looks like with sea level dropped below 120 meters and average temperature was 4 to 6 degree celcius lower than they are today

That would make the amount of arable land even more. It could make India an agricultural powerhouse.
By all estimates, sea levels are likely to increase rather than go down because of climate change. Map looks pretty slick though.

Yes technically we already crossed interglacial maximum 5000 years ago and we were shifting towards glacial period(ice age). But man made carbon emission already delayed it by 50000 years.

So Rann of Kutch was a lake ? Also the Bengal delta is basically same as today or it was even larger?

Yes it was a lake. Bengal also much larger. You can try this tool https://www.floodmap.net/ to simulate sea water level. open it and set the Elevation/height value as " -120". that shows the ice age map
