Not to take your post too seriously (recognizing the winkie), One really must wonder how long it would take the slow moving sea creatures to climb from the Bay of Bengal to the heights of Everest.
I think the current rate measured is about a quarter inch per year (or four years per inch). Making the probably unsafe assumption that the rate has been constant for the past N years:
4 (year/inch) * (12 inches/foot) * 29,035 (feet) = 1,393,680 years
Of course, that's an absurdly rough calculation, but I think it's around the right order of magnitude.
