Oh, and for the Mary question, if you actually read the bible, God "explains" himself. Only the blood of a perfect individual (God) can cleanse us for our sins, therefore, he sent Jesus. God is Jesus and also the Holy Spirit. Look up the Trinity. The Bible states that God did quite a bit of stuff after Adam and Eve were kicked out of Eden, marking the end of "talking animals" with the end of painless childbirth. Just in-case you are wondering, i am not doing this for the money lol. I am a Christian looking forward to AP. (i have made significant progress)
