Early thinkers about the nebular hypothesis were stumped by some odd things: Although most of the planets, including Earth, spin in the same direction (counterclockwise when viewed from the solar system's "north"), Venus and Pluto spin clockwise. And Uranus spins sideways!
As we understand it now, after the proto-planets formed, there was still LOTS of material left over, huge chunks of it, which resulted in lots of crashing and smashing in the solar system, which has never been a very peaceful place!
Some huge chunks probably hit Venus and Pluto hard enough to smash them spinning the other way. And hit Neptune hard enough to knock it on its side!

Neptune spins in a different direction from all the other planets because it can. There is no right side up, or sign saying "turn left here" in the Universe. If you must deliver an answer to someone tomorrow, tell tham that Neptune was formed by the collision of two objects in space. One of the objects was very heavy. When it struck the lighter object, it hit in an off center, glancing blow that started the lighter object spinning in the direction you can now observe. Over time, the spinning motion increased as the objects condensed in upon each other. The wobble one might have noticed eons ago died away as the mass of the planet became more spherical and the heaviest materials settled into the center of the planet.

Neptune spins counter-clockwise, like most of the other planets. Perhaps you meant Uranus, which spins on its side? Or perhaps you meant Venus, which rotates clockwise.
The reason is as someone mentioned above, that the planet (whichever one) got hit by some big piece of space junk at the end of formation (or several big pieces) which affected its tilt and rotation period. All the planets started out with a counter-clockwise rotation.

It's upside down.
Scientist etc. just try to explain it in a more complicated matter to sound intelligent.
So, in the spirit of intelligence here my spill. We know the Planets have a Magnetic Field. Now, from what we know of Magnetics. Opposites attract and the same opposes. We can thus assume that magnetics is involved to some extent in the function of the Spinning of the Solar System and the Planets, Moons, etc. So, theoretically the different spins and supposed up, down or sideways of how a Planet is positioned is due to a magnetic abnormality of that Planet. Just as we can magnetize a nail North/South and reverse that polarity these Planets must be Demagnetized/Magnetized over Thousands of Years before they realign and spin in the correct direction.
