Where Did All The Men Come From, That Cain Was Afraid Of?

Did you know that the popular church teaching, “All men came from  Adam and Eve.”  cannot be found within the pages of the Bible? Check it out. You will find that, on  the sixth day, Genesis chapter one states that God created man and tells them, "Be fruitful and multiply, and fill the earth, and subdue it.” However, in chapter two, God creates the Garden of Eden and places Adam in it, before there were herbs, in the field, which occurs on the Third Day. There were two separate creations of man. Didn’t you ever wonder where all the men came from, that Cain was afraid of, and why they were a threat, to his well being? Well, before Adam sinned, there was no death, in the world. Afterwards????? Well, I think that I would’ve been very angry at the descendents of Adam too.
