How did man multiply?

thats also my question before and no one can answer it even my parents, coz if adan and eve are the first human being and they only have 2 son then whose the other girl for their two son to marry and multiply with. i was thinking that maybe its also eve :) or perhaps adan and eve also have another daughter thats why.

Since your taking the bible as your reference if you go back and read some more it tells you that Adam and Eve had had many children both sons and daughter. Only three of their children are named. Genesis 5:4 says After he begot Seth, the days of Adam were eight hundred years; and he had sons and daughters. And yes Cain did marry his sister or maybe a niece.

Okay, it is called "reading between the lines". First of all, Adam and Eve had a lot more children, and I mean, A LOT MORE, after Cain and Able. Cain, it is believed, married his sister. Yes, Cain married his sister. Genesis is really screwed up if you think about it. Women are the downfall of man according to Genesis. Men and women are easily tempted according to Genesis. Now, according to science, according to Evolution, it would not be this way. According to Evolution women came first, humans evolved from apes, and people may have also mated with Neanderthals. Science has a better explanation of how humanity started than The Bible.

Why do you believe the Bible is considered fiction? Man didn't multiply thanks to Adam and Eve... It was evolution, we evolved from apes, yes that´s right APES! believe it or not science exist for a reason son. research!

Man multiplied by using multiplication table, Abacus, paper and a pen, and a calculator lol. It doesn't matter if Adam and Eve's children were boys. Mathematics isn't biased.
