Question

why our Earth is circle?​

Answer 1

The Earth is massive enough that the pull of gravity maintains its roughly spherical shape. Most of its deviation from spherical stems from the centrifugal force caused by rotation around its north-south axis. This force deforms thesphere into an oblate ellipsoid.
