This is a sci-fi movie, it has nothing to do with the Bible and/or biblical symbolism. Nice and pure piece of fiction, story of what might become of us. Contact with an alien life, justification our of intervention into natural order, men and what they carry within them to the starts are the main problems aroused by the film. A.Tarkovskiy's "Solaris" (written by S.Lem) would be the closest in a genre. One might find deeper thoughts encapsulated within the story, but in reality it has no more that any other movie would have. Easy to watch, a bit naive. I'll give it 10 of 10 for the script, 8 for the play, 5 for decorations/special effects (don't expect much). Enjoy it, should you find decent translation or subtitles.
PS: By the way, Bulychyov's book has much more to appreciate.
