So, you're admitting you know very little about science but expect scientific explanations?
Otherwise, please explain the Big Bang Theory and how the universe started in your own words.
In regards to this question, you can't have it both ways. Science does not accept the Bible nor any supernatural explanations. Moreover, there was no science then.
It also shows to me and others here that you are a person of limited scope. Science is not the onlyhttp://
www.usmessageboard.com/threads/if-god-doesnt-exist.433708/page-164#post-14651907 way to ascertain truth. We have factshttp://
www.usmessageboard.com/threads/if-god-doesnt-exist.433708/page-164#post-14651907 in which we can use to reason with and also there are historical truths. We can use law to determine what happened and who is telling the truth. Thus, I use facts, reasoning, historical truths and other methods including science to ascertain truths while you are limited to your narrow science. Tsk.
The word serpent is clearly explained as a snake in the Bible. I gave you the passage, so you can look it up yourself. We know animals cannot talk even though a parrot or other birds can copy what was said.
As for the rest, this happened outside our realm which is timeless and spaceless. God created angels before His other creations. ""Where were you when I laid the earth's foundation? Tell me, if you understand. Who marked off its dimensions? Surely you know! Who stretched a measuring line across it? On what were its footings set, or who laid its cornerstone - while the morning stars sang together and all the angels shouted for joy?" Job 38:4-7
He also created free will. Angels are spiritual beings who have personalities that include emotions Luke 2:13-14, intelligence 2 Corinthians 11:3, 14, and wills 2 Timothy 2:26. Satan was an angel who was cast out of heaven along with many other angels who decided to follow him and chose to sin 2 Peter 2:4. In terms of free will, the Bible reveals this was an exercise of their ability to choose Jude 1:6.
During this time, He also created heaven which is explained in Genesis.
Because of free will, there were some powerful angels led by Satan who wanted an equal or separate share of heaven and to rule like God. They were banished because they disobeyed God's will.
God created all the angels then and there will be no more. Angels in the material world refer to messengers, prophets, priests and church leaders. For example, if someone sends you a telegram and they were instructed to read it to you, you are not going to question how they know something about you or your situation. The message is what's important.
Thus, Adam and Eve did not know animals weren't suppose to talk. They just accepted it and the message being delivered.
