Worse, you have a group of four planets with the same 23 - 26 degree tilt i.e. Earth, Saturn, Venus, and one other which no impact would cause. What appears to be the case is that our system is a composite system, i.e. a larger system including the sun appears to have captured a smaller one.
And another thing to remember,
Uranus spins sideways.
