According to Wikipedia it takes 248 years for Pluto to orbit the sun! Sometimes it's eccentric orbit brings it closer to the sun than Neptune!

Does that mean eventually Pluto will crash into Neptune in the absence of something else taking them out first?

Apparently not. There are 2 reasons for this: while Neptune's and Pluto's orbits overlap on images, they overlap in such a way they never overlap on the same 3D point in space. Ther is also gravitational resonance[2], where each planet speeds up or slows down as the other approaches

Job of planet: clear entire orbit.

Requirements for candidate: must have already cleared entire orbit.

Prospective planet: ...

Agent: how about you clear your orbit as an intern, first.

According to creationist we can't know the orbit of pluto if we haven't seen it make an orbit.

Pfft, our moon is bigger. You're just a big ass comet that can't even do that right to get a tail.
