Relativity Theory
Spoiler Alert,
So humans are exploring a foreign world. They deemed it no signs of intelligent life form until they see some primitive lizard like creatures. So they kill two of them to investigate what they are. But it turns out they're little alien boy scouts on a camp! The humans get a stern talking in lizard alien tongue from a probe shot from a worm hole. Then they blow up? The next thing you see is a huge alien craft on its way to Earth. Are they going to blow up earth too on a misunderstanding? It seems like the Aliens are always more violent and irrational than the Humans at the end for our missteps.
