It's simple to you, and as I noted, it's a good theory. But the bible doesn't SAY that. You're inferring what the bible MEANT because you are confronted with an obvious contradiction. Luke doesn't say Heli was Mary's father, he says, "Joseph, of Heli" when Joseph was not of Heli.
If you had never read Matthew, and had only read Luke, and I tried to tell you that Heli wasn't Joseph's father, you would say I was saying God was lying.
Likewise, 400 years ago, you would be insisting to me that travelling to the moon would be impossible, because there was a firmament seperating us from the moon.
And 800 years ago, you would be insisting the Earth was flat, because the bible plainly speaks of the "four corners" of the Earth.
And you insist that there is no contradiction between Chs. 1 and 2. Yet Chapter 2 says Man was created before the plants grew, because there was no rain from above and no-one to till the Earth. Chapter 1 says the plants brought forth abundance three days before Man. You had kinda skrited the issue by saying that chapter 2 didn't happen all in one day. Fine, but it still says that Man was created before plants were.
