Why be good?

[Exian]

I'm always aware of the increase of words like "eye-witness" when discussing the NT. It's as if as time went on, and civilizations evolved and grew, the writers were aware of the need for witnesses for the sake of believability. A thing that is missing from earlier writings in the OT, as if there was a time where simply asserting something was good enough. You'll notice nobody talks about a witness when discussing Adam and Eve talking to a Snake, or god separating night and day. Its as if things were just accepted, but by the early centuries C.E., suddenly we see qualifying situations.

But, that's the OT. That's completely different than the NT. Nobody believes that nonsense.

I'm not into Genesis 1-3 as a literal account personally, but let's say that it was.

Adam and Eve were the only people on the planet at the time. Who would the eyewitnesses have been? 

And when god was creating everything, there were zero people on the planet, and yet, your book gives us an account.

But, like I said, that was a different time, when you could write down any assertion and have it be believed. A convenience not enjoyed by the time of the NT authors. They seemed to need to qualify their stories in their more evolved civilization.
