Good question. Scientists will tell you all sorts of things. But remember, science has a LOOOOOOOOOOOONG history of being wrong.
Over the centuries science books have changed A LOT! And they are still changing. Why?
Cause they are always wrong. Who's to say that what scientists teach now isn't the same way? Who's to say that what scientists teach now will one day in the near future be thrown out as ridiculous "old theories"?
The answer to your question is this: there was no asteroid that killed life on earth. The flood (Noah's flood) killed the dinosaurs. Life returned to earth by the life that was living in the water, and life that was living on the Ark.
Your facts are wrong--the asteroid that killed the dinosaurs did not kill all life on Earth. In fact, it is widely known that all current-day mammals, including humans, derive from a small creature that survived the asteroid impact.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
