Did people originally come from Africa and Australia?

-I'm asking this question because I was watching the tv and this professor dude was talking about Mungo man and Mungo women found in Australia! He said that they were over 40,000 years old and they are different because they share no DNA thing with any Africa thing? How comeWhy are you even comparing Australia to Africa? I don't understand the connection. Australia was originally used by the English and others as a prison basically. You sent criminals there. I am most certainly not saying that there couldn't have been native people, as I am part Australian and they are a wonderful people. My Aunt and one of my Uncle's were born there and came over to the US with my Grandma when she got remarried, to my Grandfather. But what Africa has to do with Australia...??
Africa...some of the oldest discovery of human life made in South-Africa in the cradle of human kind.
"they are different because they share no DNA thing with any Africa thing?"



I hadn't realized Africans were referred to as 'things'.
Mungo remains prove that all people did not originate from Africa. There are still too many gaps in our knowledge to have more answers than that unfortunately.
