This curiosity is quite understandable. But when you check up with the answers they get, it often would be a great disappointment.
But let me tell you a secret. There is a super authentic information now available to us in the form of a huge english language book. A book of revelatory knowledge given to human kind from superior sources !
Let me first tell you in brief what this book reveals about the first human beings of earth. This is some thing like this :
The first human beings ever to be born on Earth were a pair of Twins, one a boy and the other a girl, born to a pre-human ape family. That means their parents were not humans, but a lemur type tree living animals, now extinct.
