I Referential inertial

Summary
How we talk about referential inertial if the Earth always is in motion? Because if the Earth is in motion, everything is in motion with the Earth. So nothing is a inertial referential.
How can we talk about Newton's First Law?

An inertial frame of reference in classical physics is one that is moving at constant velocity. The earth’s surface may be considered as an inertial frame, although in theory it is non inertial because of small centripetal forces etc which are often neglected because such forces are not significant in many examples.
