Because the Ten Tails has what is confirmed to be a Rinnegan, specifically the red, tomoe'd variety.

Fair enough. However, never once have the tailed beast been associated with the Rinnegan. In fact, we don't even know where the Rinnegan showed up first. It is just as likely the tree got the eye because of Kaguya as it is the other way around.
