In the beginning, Adam and Eve were in Paradise, They did not know good from evil, because they was no reason too. When the serpent ( He may not have been a snake as we know them today. Because God said to him that because of what he had done he would now have to crawl on his belly. So it is possible the serpent had appendages at that time.) When Adam and Eve were banished from the garden of Eden, They now knew good from evil and had experienced sin. As a matter of fact they were indwelt with sin. That is why we are born into sin, and the fair judgement is death. Jesus who fully God and fully man, came here for one reason, and that was to give us the gift of grace by exchanging what was rightfully his. That was righteousness, for what was rightfully ours, the judgement of death for sin. Jesus died on the cross for one reason to die for our sins. Jesus also said the ONLY way to the Father was through Him. If you don't accept Jesus and develop a relationship with him, you will go to hell. There are no if's and"s or but"s about it, and there is no door number three.
My prayers for you my friend.
P.S. Food for thought, since we are all direct descendants of Adam and Eve, we are all related. There is no other races but one. The Human race.
