The role of the parameter part here is to act as a reference to the output of the Touched event on BasePart.

According to the Official ROBLOX Wiki page about BasePart, the Touched event returns a reference of type Instance to the object that came into contact with the 'host' Part.

It is possible to ignore the values passed by an event, for example:

function Touch()  --There are no parameters, so the touched Part reference is 'dropped'
   print("Nothing Special")
end

script.Parent.Touched:connect(Touch)

The purpose of a parameter, in this case, is to provide a reference to a Part Instance.

Part is the part that touches the object, and the 2nd line is basically checking if the part has a humanoid.
