One of the first concepts for the ark was that it comes from UFOs, as we could read in the Raiders transference transcripts (1979):
LUCAS: "The Ark is like a radio transmiter. That's the real legend. That's what they used to do. The Israelis used to set up these tents and they would talk to God and God would tell them what to do. And then they would march with it in front of their army. The other Armies would be destroyed. Our idea was that there must actually be some kind of super high-powered radio from one of Erick Von Daniken's FLYING SAUCERS. The fact that it's electrical charges makes it vaguely believable."
Phillip Kaufman also mentions the extraterrestial connection:
" (...) when I was in college, a famous blood specialist had written
with another doctor an article on the Ark of the Covenant
and how he felt it provided a means of communication with some
other extra-terrestrial or God-like or whatever. It was in
a sense an elaborate radio setup. It contained silk curtains and
veils and other things."
So all the criticism against KOTCS about aliens in a Indy movie is strange. In fact the opening of the ark is very similar to the last section of Close Encounters (Released only 4 years before) and the warehouse with top secrets crates must have alien artifacts.
