It's more than that. The story of the seven sisters is in many different cultures and the story is usually the same: seven sisters chased into the sky by a hunter. Most also have a story about the seventh sister leaving the sky or simply fading away.
The real evidence is that the same story exists in aboriginal Australian culture, and has been since well before first contact with Europeans. Most likely the story was brought with the aboriginals when they left Africa and has been told ever since.
Seriously, read the Wikipedia article or watch a video about it. It's an extremely interesting topic, and learning about it is a lot more fun than just assuming it's wrong and everyone is stupid.
