My interpretation of Kalki Avatar

Hindu Mythology says:

The tenth and the last avatar, or incarnation of Vishnu, Kalki, is yet to appear. Kalki will appear seated on a white horse with a drawn sword. He shall come finally to destroy the wicked, to restart the new creation, and to restore the purity of conduct in people's lives.

I could interpret this Kalki story to reality like this: The white horse is nothing but the clouds(sky) and the drawn sword is the blazing of comet.
So far the Earth is being protected from comets, thanks to the gravitational pulls of Saturn and Jupiter.

Nostradamus predictions says:

Le monde proche du dernier periode,
Saturne encor tard sera de retour;
Translat empier devers nation Brodde,
L’oeil arrache a Narbon par autour.
111.92

The world approaching its final period,
Saturn will again come late to his return;
The empire will be changed over to the dark-skinned nations,
And Narbonne will have her eye picked out by a hawk.

Toward the end of this great round, the black and brown nations will come into their own as centers of world power, and the French and other European nations will lose their supremacy. We are now entering the final phase of the old “world” or age, and the Third World nations are indeed coming into their own. This indicates a coming period of great ascent for brown and black races in the new order

If Nostradamus predictions are to be believed and the Mayan calendar applied then there is a possibilty of an asteroid/comet hitting earth between 2012 till 2020 causing partial extinction during the transition period.

We also believe that a collision from an asteroid was responsible for the extinction of dinosaurs from the earth 65 million years ago.
