1. How can you be so sure that the end of ice age did not have an extraterrestrial
source?

2. You list what actually happens in our solar system. With one error. The Tunguskan
explosion was not caused by a small black hole, but by a very common type of stony
asteroid.

3. I have nothing against of calling the ice-age-ending event "Niroma hypothesis"!

4. The extinctions surely are an interesting thread.

Kindly,
Timo
