questions on humans v0.1

So ... time to do some of my own research, with no twitter distractions from the Twitter world :-)

Now I have been discussing things with religious folk, but I am getting out of my depths because I know nothing on the topic.

So to educate my self, I have found that New Oxford Annotated Bible  is the most used bible by theologians of many religions.

Questions before I begin to read which I would like answered during my learning, and these come about from My current understanding ?

* Why was Adan and Eve given 1 law: not to eat the apple, but Moses gave 10 commandements ?
-Was it a law or suggestion ?
-Was it because there was a snake/devil on the tree?
-Was it for their protection so that the snake/devil did not bite and kill them / influence them ?

* How did God speak to them ?
- Was it from above -> heaven ?
- Was it from above -> their heads / minds ?

* Question I need to look into from science ?
-when did consciousness come to be in humans ... because it has been found in animals that existed in humans ?

* Could the start of consciousness, coincide with Adam & Eve ?

* Could conscousness be the start of humans and hence us understanding our roles and responsibilites on earth, rather than laws given from God ?
-Or were these laws given from above -> ours minds -> God ?
-Is the law to be guardians of what we have around us ?

End for now
