1) Ice age after the Flood kept things cool. Ice age also a product of whatever heat is generated in tectonic and volcanic events.
2) I never said tectonic events such as the raising of the Himalayas took only a few years. Sorry if I said something that could be interpreted that way. However I certainly don't think such events took millions of years, a few hundred would be more than enough.
3) There were no people in India for at least that long, and besides all they'd experience would be earthquakes.
Excuse me if I feel free to guess about such things, but that's what Science is doing too.
Honest guessing is quite alright. Science OTOH does not guess per se.
The amount of heat generated by very rapid tectonic movement cannot be countered by any ice age, especially since one cannot assume that the movement had quite suddenly groung to a halt. The plates move as they have for millions of years.
It is rather silly to think that peeps in India had been able to carry on with their daily life when greater earthquakes that have ever been recorded would have happened in "their backyard".
You are persistent and hard-working but when your basis is so fatally flawed, it is nothing short of amazing how you just carry on. There is absolutely no way that the earth we see today was mere millenia old. There is recorded history for longer than that.
