Just don't read into it too much. Thats causes confusion and curiosity. I remember being gathered around these two people that got deep into the beginning of the earth. I found myself being curious about it. then God spoke and said clealry, 'If you get too deep into it you may be driven astry, Just believe what I say"Just believe what God says happened. Thats the problem everyone wants to know why, why, why, why, Just believe what God says.
