Hm. Perhaps we should pander to the historicity.

King/God Lord Ram 1.7 million years ago, with an army of monkeys built a strip of land (which has existed for 5-7 thousand years) to rescue his wife Sita. Now the Indian government wants to build a canal through that strip of land (built by the army of monkeys, 1.7 million years before it existed for the first time).

It's totally historical! It should be a monument to how awesome Ram is.
