But nowhere else was.
As the earth spun on its axis. And the earth moved around the sun.
The space-spores kept landing on Kerala.
Right. How does that work, exactly?
Meteors burn up in the mesophere, about 40 miles above the earth's surface. There is weather up there, but not the normal wind patterns that we are used to. There are standing waves and strange weather phenomena like notilucent clouds up there that we don't fully understand; also, some gasses separate there, impossible at the higher temperature and pressures which we are used to. A trail of dust debris from an incoming meteor may take much longer to dissipate in the mesosphere than a cloud of the same size lower down.
Making it even less likely that it would all land in the same place.
Adding unusual atmospheric phenomena on top of everything else just makes this more and more absurd.
Nor am I not suggesting any unusual atmospheric phenomena; I'm pointing out that that part of the atmosphere is known to differ substantially from lower altitudes. Multiple interacting tides, for example: http://en.wikipedia.org/wiki/Atmospheric_tide
