If you read the new making of the indy films book, it says --
George and Steven both say the idea is that these ALIENS CREATED THE HUMAN RACE.
Well, YOU CAN'T DO THAT when you already had Indy 1 and 3 prove that the stories of God and Christ are true.
Also, it says Steven and Harrison BEGGED to make another Indy for 15 years. George always said "Not unless it has ALIENS and UFOS!" and that's why Steven and Harrison wouldn't do it. They thought that idea stunk. They finally caved and Lucas got his sheety movie.
