Please explain why the Eclipse is starting from the west going east. We all know that the sun rises from the east.

Essentially, the Moon and Sun “rise” in the east and “set” in the west because of the Earth’s rotation.  The eclipse moves from west to east because of the orbital motion of the Moon.  That’s really it, and there is a great animation by NASA that shows this.
