RWBY Theory debunked: Qrow is Ruby's father

Debunking

So first let me explain the evidence that people have the picture the fact that Ruby fights like him and they have the same color hair.. So now debunking it bringing the picture up last. Why does Ruby fight like him well it could be that Ruby actually looks up to Qrow or wants to fight like that and she knows he is the best person there to teach her how to fight with a scythe no need to make a theory from it. Now that they have the same hair color well Summer is a natural brunnete so Ruby inherrited that from her mother. Now what does debunk this theory is how the creator said to another theory that Ruby and Yang are half-sisters so I know diffrent theory but still if the creator said they are half sisters then wouldn't this theory be debunked like if Qrow was Ruby's father then wouldn't Ruby and Yang would be cousins. Now the last theory is Qrow's picture all of the tears on that picture is by Summer but hey that doesn't mean they had Ruby but here is my theory that after Ruby was born that Qrow and Summer had a relationship of more than friends like romance but hey tell me what you guys think about my theory
