My mechanics teacher assumed it was obvious right from the start and I finished the first two mechanics modules and I'm still left slightly confused about the reaction force

When an object is lying on the ground, its weight force is acting downwards. The object is clearly not going through the ground but staying in place, so its weight must be balanced by an upward force. This is the reaction force which the ground exerts on the object.

Another example is: gravity pulls you towards the earth's core, the earth's crust opposes the gravitational force.
