So, I was thinking about some interesting things earlier. I've heard that in the Bible it states that humanity started off with two people, a male and female. But these were the first to people ever to live, and if there isn't an explanation for this in the Bible, then... How did they know that they needed to drink water when they felt thirsty. Why didn't they go and eat sand and run away from each other? Just some thoughts I had, any ones opinions?
