So what's the point about Planet Nine?....the point is this: that they don't yet know our own solar system enough yet to know how many planets are in our own backyard.....so why believe everything they tell you about deep time and the universe?
Where wast thou when I laid the foundations of the earth? declare, if thou hast understanding.

planetary scientists Konstantin Batygin and Mike Brown present what
they say is strong circumstantial evidence for a very large undiscovered
planet, perhaps 10 times as massive as Earth, orbiting in the solar
system’s outer darkness beyond Pluto. The scientists infer its presence
from anomalies in the orbits of a handful of smaller bodies they can
see. 
The object, which the researchers have provisionally named “Planet
Nine,” comes no closer than 30.5 billion or so kilometers from the sun,
or five times farther than Pluto’s average distance. Despite its
enormous size, it would be so dim, the authors say, that it is
unsurprising that nobody has spotted it yet.
In 2014 Trujillo and Scott Sheppard, of the Carnegie Institution for Science, argued in Nature that their own discovery of a much smaller object, called 2012 VP113
, along with the existence of a handful of previously identified bodies
in the outer solar system, hinted that there might be something
planet-size out there. The evidence lay with their orbits, specifically
with an obscure parameter called the “argument of perihelion”—the
relationship between the time a body makes its closest approach to the
sun and the time it passes through the plane of the solar system. The
objects Trujillo and Shepherd identified all had uncannily similar
arguments of perihelion, which could mean they were being shepherded by
the gravity of an unseen world." SA
