No, an amorphous solid is not a liquid.

A liquid is: “a nearly incompressible fluid that conforms to the shape of its container but retains a (nearly) constant volume independent of pressure” (from Wikipedia).

An amorphous solid does not flow to conform to the shape of it’s container. Thus, and amorphous solid is not a liquid.

Further, many solids are non crystalline. Wood for example. Also charcoal. Also paper.

Are you seriously planning to argue that paper is a liquid?
