I have seen this sci-fi movie once in TV, around the 90's second half.

In this movie, a huge UFO was found near North Pole (or was the south?) and a expedition is called to go inside.

Inside the UFO, I remember they found lot of test tubes containing fetuses. The fetuses were human-like and, I think, alive.

In the moment they handled some of the UFO controls, it started a signal to somewhere in the sky. Sciencists start to analyze the signal and they interpreted it says something like "the food is ready". Later, they found some "plans" explaining how life was started on Earth and what will happen in a evolutionary process as we know today.

They discover everything happened as "they" planned: life in Earth started, evolved, civilization raised, cities were built, technology accelerated, we discovered and entered the UFO, handle the controls and send the signal. All of this, predicted thousand of years ago. And... the most concerning part, we sent a signal to the beings that will use us as candies or part of a huge barbecue.

In the final scene, the Earth defense forces get their radars saturated with hundred of UFOs. 

They don't show the extraterrestrials eating us, but that's implicit. No happy ending this time.

Did somebody watch this and can tell which story is based on... or movie name?

I asked some IA and told me this film is called "Independence Day", which demonstrates IA can make jokes too.
