However, we are NOT happier, nicer or better people--not ONE iota.
We are STILL Adam and Eve and some of us still INSIST on believing in Lucifer's lies. There are even Satanic cults. How EVIL and useless is that?!
When limited to a very narrow relevant range of time, that might be true. But this is a relative characterization.
Throughout history, life-spans have fluctuated, depending on the level and refinement of civilization. In the Dark ages, 35 was considered old, but in the antedeluvian, and even into the post-diluvian period, people live for hundreds of years.
Similarly, levels of education have fluctuated drastically through the eons.
But you are right. Morally, we are exactly the same the first two beings.
