According to Cosmos, why are there so many stars?

Stars form from the diffuse, cold interstellar gas that makes up molecular clouds! These clouds spend roughly 100 light years And hold between 10,000 and 1 million solar masses of material! It already has churned out thousands of stars and thousands more are growing inside dark clouds of cold hydrogen.

This probably doesn’t make sense

south africa, or rather all of africa, has not been in the location in which it is nowadays throughout the geological past. after the super-continent pangaea started to break apart, gondwanaland, in which was africa, moved further south, and parts of it came to be very close to the south pole. because the climate in this part of the world is very cold due to the very dispersed sun rays in there, what is now south africa, started to freeze, and the conditions were right for the formation of glaciers. the glaciers existed up until the period when gondwanaland started to break apart and what is now africa started to move towards north, sp it warmed up and the glaciers melted.
