Was Adam Truly The First Man On Earth?

The Big question is " How did Man come into

existence"?. The many religions we have today and

those of the old gods possesses different beliefs on

how Man came into being.

As a Christian, i learnt through the bible how Man

came into life and I don't have to share it because I

believe everyone knows that including non

Christians because am not here to quote the Bible

as am not that religious.

The generally known belief on how man came into

the world is best explained through academia which

states the evolution of man proposes that humans

and apes derive from an apelike ancestor that lived

on earth a few million years ago. The theory states

that man, through a combination of environmental

and genetic factors, emerged as a species to

produce the variety of ethnicities seen today, while

modern apes evolved on a separate evolutionary

pathway.

My BIG question is, which should we believe and if

Truly Adam came 1st from God, how then did he

populate the world to what it is right now?.
